simple..do something you are passionate about.
if you are not passionate about ,what you are doing, then find something else..
u will even get stressed and burnt out doing the things you have a passion for..not just work, but family, kids..and for that a couple days break from whatever is burning you out helps.
Having passion about your selected profession should be the most critical factor .........Although I admit I didn't choose my profession just because I was passionate about it, there were other factors too.
