"scientists don't want you know" is a phrase that always cracks me up because if you actually meet a scientist they will be shaking and crying like an overstimulated chihuahua with the need to let you know
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
