Each of us will have a job that we either love or that we tolerate because it helps pay the bills. In some cases you could have a job that you dislike and is making you unhappy but quitting would be the last decision you made as it would mean that you would lose the money until you found a new job so you stick with the job regardless of it making you unhappy. 

If you were in a job that was making you unhappy, would you quit and leave regardless of if you had another job lined up?
