Zest (positive psychology)
In positive psychology, zest is one of the 24 strengths possessed by humanity. As a component of the virtue of courage, zest is defined as living life with a sense of excitement, anticipation, and energy. Approaching life as an adventure; such that one has “motivation in challenging situations or tasks”. Zest is essentially a concept of courage, and involves acquiring the motivation to complete challenging situations and tasks. Those who have zest exude excitement and energy while approaching tasks in life. Hence, the concept of zest involves performing tasks wholeheartedly, whilst also being adventurous, vivacious and energetic. It discourages the focus on the negative views of psychology. It embraces a notion that one must observe people that "live well" in order to truly understand positive psychology. (For example, a Buddhist monk would be a preferred subject of observation compared to a college student.) Zestful people simply enjoy things more than people low in zestfulness. Zest is a positive trait reﬂecting a person’s approach to life with anticipation, energy, enthusiasm and excitement.
Christopher Peterson and Martin Seligman developed terminology to describe human strengths. They developed a descriptive list of six human virtues (Wisdom and Knowledge, Courage, Humanity, Justice, Temperance, and Transcendence) comprising 24 strengths. Zest is one of the four strengths that combine to make up the virtue of courage, as defined by this system.
The VIA-IS is a self-report questionnaire that assesses the strength with which respondents answer strength-relevant statements about themselves on a 1-5 Likert scale. The following statements on the VIA-IS are used to measure a persons zest: I look forward to each new day; I cannot wait to get started on a project; I want to fully participate in life, not just view it from the sidelines.
As with many of the other constructs in the relatively new field of Positive Psychology, it is difficult to quantify zest. Other traits like socioeconomic status, which can easily be measured by gross income per household, or constructs like fear, which can be quantified by changes in heart rate, skin conductance, and pupil dilation, have much more defined and widely accepted methods of measure. However, measurements of Zest are still in the beginning stages of development. How do we measure how energetic one person is compared to another? How do we determine exactly how excited a person is about life? What precisely does it mean to approach life adventurously? These are just a few of the questions that must be answered to most effectively research zest.
Relating to the problem of operationalizing zest, much of the research currently done on this and many of the 24 character strengths are done via self-report. A Self report study is one in which participants are simply asked to report their own feelings or thoughts. There are many problems in research associated with self-report. The most pertinent one being the validity and reliability of measures as they are completely subjective rather than objective. People can misrepresent themselves or misinterpret the questions posed to them.
Since such data is not the most scientifically convincing body of evidence upon which to rest scientific conclusions, Positive Psychological research is very focused on developing more objective measures for topics such as zest in order to help build a stronger science of organizational behavior.
Zest can be promoted in the workplace so that workers can have a more positive approach in their life which indirectly can affect their anticipation, excitement, and energy in the workplace. Evidence from a present study, that had 9803 employed adults respond to a survey on an internet site, measured zest, orientation to work as a calling, and satisfaction to work and life in general. The survey predicted, to many of the employees, that work was a calling and a satisfaction. Employers can use such information to really up the productivity of their employees by taking zest into consideration. The study found that professionals had the highest zest, while clerical workers and homemakers were the least zestful. Professionals and homemakers viewed their job as a calling, while clerical workers were the least likely to do so. Clerical workers displayed one of the lowest levels of zest because in most instances they viewed their work as a career, a pedestal in the hopes of acquiring status and power to find a more suitable job for themselves in the future.  The results of this study follow trends observed by many other studies as well.
Zest is speculated to be contagious just like many other strengths of character. Zest is obviously connected to, if not equal to group morale and can be a point of discussion for new studies from a positive organizational perspective with emphasis on zest. Psychologists have learned about two main ways of promoting zest within workers: physical fitness and health set the tone for zest and it can be sustained through hope and optimism. Depression is a well-documented enemy of zest, and its toll on productivity and physical health is enormous. The prevention or reduction of depression among workers might pay the additional beneﬁt of increasing their sense that work is a calling.
Zest is also linked to psychological well-being which is crucial in a work organization. For instance, psychological well-being predicts improved job performance, reduced absenteeism and reduced turnover. These are all benefits that can be explored more critically to make changes in the workplace.
Increasing zestfulness is highly likely to increase the ability to be habitually happy. 
Positive youth development
Zest can be applied in every aspect of life to bring out a positive change in each individual’s life. It also has effects in groups, communities, departments and offices. People are taught to take life’s hurdles and obstacles as challenges and face them with bravery and an open mind. Zest, along with gratitude, hope, curiosity and love, are important aspects of positive psychology and key to positive character development. The adequate promotion of these characteristics not only in domestic life but also in schools and other educational environments is extremely important to positive youth development. Furthermore, through promotion of character strengths such as zest children tend to experience fewer psychological problems such as depression and anxiety disorders. They also tend to excel academically and lead happier, brighter lives. More emphasis needs to be placed on positive developing characteristics such as zest, gratitude, hope, curiosity and love in schooling environments and live in general so that youth successfully and positively develop. Zest encourages emotions that can benefit the employer. For instance, a positive work environment (safety, friendly, welcoming) can in fact encourage the worker to perform tasks that will increase business and profit. If one works in a retail store, and they are motivated with zest, then they will act happily, increasing customer satisfaction.
