Pushing 4 decades, and the older I get the more I try to live by a philosophy of: be the person you wish you had when you were in their shoes.
Biggest thing is school right now: I did the college thing a bit a long time ago, struggled academically and financially, joined the military instead, separated, and now I'm back for round 2 using the GI Bill. I try to generate as many resources for my classmates as possible, run study groups, host group chats, send out reminders... The VA gives me a stipend for supplies each semester, which I'll use in it's entirety and give those supplies to the class. At clinicals (on-the-job education - nursing school) I've noticed a few students don't eat cuz weren't able to pack a lunch and hospital cafeteria food is WAY expensive for the average broke-ass college student, so I'll cover the odd meal and tell em to just pay it forward once they get their RN. Shit like that. Kinda feels like I have 50 sons and daughters lol. But I remember my first attempt at college and how overwhelming everything felt... idk if having a 'me' would have made any difference in the outcome of round 1 - can't make the horse drink and all - but if I can hook these kids up with an easier ride, then fuck yeah I'll do what I can!
I try to apply that kind of approach to pretty much any context - be it school, work, or just random encounters with people.
Feels good to be helpful.
