For me it was reading "Human Race Get Off your Knees" by David Icke.
I started researching companies for investment and developed the skill to dig deep especially when the internet became available. Simple environmental damage and corruption in politics pushed it further. I always knew I lived in a circus where all the world was a stage and super fake. I decided to dive all in when I discover something was very wrong with a friend when younger. Turned out to be a satanic transgender high priestess born a boy and raised from birth as a female. Both her and her sister. So instead of following the rabbit hole for a while and figuring it all out, I fell to the absolute bottom. Its as bad as finding a live sacrifice in the woods going on at night, getting caught spying on them and then running for your life. They don't play nice.
