trusting your gut is a good call. I think most people on this board are pretty introspective and analytical, and there is nothing wrong with that, but sometimes you gotta be able to turn it off.
do i want to go for that job
do i want to talk to that girl
sometimes you're better off just saying fuck it and going for it.
work can be shit & thats why they pay you for it. being an adult means sometimes doing things you dont really like.
I used to do a lot of manual labor with my dad. once i asked him if we should take a break, and he said "the first time i want to take a break, i just go back to working. the second time i feel it then i take my break". I learnt a lot about hard work from him.
Another useful thing is to think about worst cases. Lets say you do the six weeks and it doesnt work out. Whats the downside? 6 weeks of your life? Dude that will pass so quick you will barely notice it. Would you have these doubts about saying fuck it then? Would the experience help to get a similar role somewhere else? Would you have any internal dramas about taking your holiday?
