All that wealth is great, and may even make a difference if you catch cancer. Or not. One famous chap who is nailing it is Shatner. Strive to be spreading joy like that guy, whatever your means.
Shatner has always been a jerk, the joy you're seeing is manufactured PR for a man who is worried about his "legacy" like any of the other older rich.
Picard, Sisko (spelling), Janeway
I hope none of them are bad people IRL, they didn't give that impression on the little screen.
