Wordy title, simple post. Find someone younger and work with them. Teach them things, but let them teach you as well.
Enjoy the process with no agenda, no “expected outcomes”. Just find a friend somewhere, and enjoy helping them, and enjoy learning from them.
Except the really nice feeling you get just before you fall asleep. Because you aren’t doing much – just making a friend.
And making friends is like holding baby rabbits – everyone loves the feeling!
