Whats different about psilocybin?

Can someone explain, preferably from their experience, how a psilocybin trip differs compared to just like regular self awareness. Like i feel like a lot of people know that they overeat or have a social media addiction or dont exercise enough or something, so if they know it normally and cant seem to fix it how does psilocybin change that, considering they already know the problem

Genuine curiosity, just confused about it all
