What's tricky is communicating the personal profundity of a message, beyond the text. The context of your life shapes the words into something resonant. Ergo, I'd feel like a bit of a wanker trying to spout off something that sounds like deep observation, but might have only been relevant to me at a certain stage of development.
Instead, let me relay some nuggets of unsolicited wisdom passed onto me by various drunks and junkies, they found distilled in the bottom of the bottle, or the ass end of a shot caking the mouth of their syringe.
"You can't know beauty, man, unless it's INSIDE you. You gotta have it INSIDE you to see it out there!" (drunken barfly)
"You get the women. And you fuck them" (random bum. thick accent. his unifying theory of life)
"Don't let anyone tell you who you are; you can be whoever you want" (lapsing out of consciousness, gear still in her arm)
"We can't be people like we used to. Cellphones and internet got us watching out back against the people ain't gonna do us" (another bar freak)
"My friends left me to die. And I'm here again" (some guy flying on acid who approached our camp fire / site out of the fucking woods. startled us, but he was too wasted to hurt anyone and we felt kinda sorry for him so we let him stay and have a beer). We called him Igor.
"It'ssss too mucking fuch..." (despondent man crying into the bottle of mouthwash he was drinking at 4AM)
"Life is like a box of chocolates" (adult man with learning disabilities played by academy award winning actor)
...
No real point to these. Just some perspective from the crust. Everyone thinks they know how things work, whether they're a homeless trainwreck, a successful worker or a CEO. I think it's braver to admit you don't - and in an epistemological sense, can't. (the big picture - life the universe and everything)
