If your default live model is going to school, then going to unviersity, partner, kids, work, work, living daily live, getting old, dying and you are happy and content, great!
But that image is not true for a lot of people for a lot of different rasons.
LSD gave me a lot of empathy for people who have some mental illness for example. MDMA gave me a very empathic experience i never had before.
And just getting old might be a goal for people, also something like not dying but again, thats just a default thinking not necessarliy what other people conclude for their lives.
