telling your brain "i know you don't wanna do the thing and it'll be very uncomfortable for you at first but you can do it buddy. it'll be fine" is actually surprisingly effective. it sounds too simple but that fuckass organ WILL listen to you if you treat it with kindness lol
I'm a big fan of the "GPS Theory" when you miss a turn, your GPS doesn't judge you, it recalculates. No matter how many detours you take, it finds another way forward. Life works like that too. You'll make mistakes, but your destination doesn't vanish. The route just changes.
