should we really just trust our instincts?

hi!! as im figuring out adult life ive realized that most of the time when i wanted to do something but doubted my instincts and ended up doing something else or following someone else's advice, ive regretted it. badly.

but at the same time i know im young and young people do dumb things and make immature decisions most of the time.

im the kind of person who is terrified of making mistakes, even if i know that it is impossible to die without making one.

so i just want genuine advice, to what point is it worth it to always trust our instincts and gut feelings?
