Gambling is a very tricky thing. It can get out of hand easily because of how the brain works. That initial “rush” of excitement starts to burn pathways, and causes chemical reactions that need to be fed more and more.

If you want to be a genuine grownup, read (or listen to) everything you can get your hands on.
“Racism is real, even if you aren’t a racist. White privilege is real, even if you don’t feel it. Police brutality is real, even if the cop you know is kind. Your world isn’t the world. Everything is not about you.” -Mohamed Safa
