Neuroscience

this is called neuroplasticity 

you can literally rewire your brain and change the physical structure of it. the more you “exercise” specific neural pathways, the stronger that pathway becomes 

you can also create completely new connections in your brain thru new experiences

start painting and doing it over & over and your brain will physically change to accommodate those creative pathways. this is why u suck at things when u first do it, b/c your brain literally doesn’t have the functionality to do it yet. but you can build it up over time

same goes for if you DONT do something. stop painting, and you brain will slowly weaken that pathway

Exactly! Same with making changes to personality and becoming a different person. It takes work but it’s possible
