Make it clear that you place happiness high up in your list of priorities, not only to your future employers, but also to yourself. It isn’t silly or naïve to want to go to work in a cheerful place; it is productive and rewarding. In fact, your workplace can be a highly competitive environment, filled with ambitious goals and it is still possible for you to leave the office at the end of the day with a genuine smile on your face, as long as you know that what you want to achieve there can make you happy.
