I would like to ask whether you ever had this feeling you took all wrong decisions in your life. You do your stuff every day and you keep thinking about how many other things you could do, how much time you do NOT have to do what you enjoy, how many other people you could meet, in which other place you could be. You start dreaming and dreaming, and then you stop thinking about the relative safety your job and daily life gives you, and then you start again. Many job seems better than yours, many places seems better to leave than when you are.
