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
Major life hack: Don't complain, ever. Nobody likes a complainer. They drain the energy of everyone around them. It's exhausting spending time around someone who constantly complains about things outside their control. If it's within your control, go do something about it. If it's not, you're just wasting energy thinking about it. Complaining gives too much power to the thing. Take back that power.
