For me it seems evident but people are always surprised when I say it: You should do what you like or something "related " enough . My motto is that whatever you do, some days you will hate it. Doing something you like make you go back faster on your passion and the reason you are doing it. I mean at the end of the day, when you are lying wide awake on your bed, no one is going to be happy for you if you are not happy yourself.
