Think about what you really want and what makes you truly happy .
To not die; to not age; to experience continuous growth (not in the pituitary gland/gigantism way...)
Don't do things to make others happy
Each to their own, but that sounds FU.
I think what he meant was to not be a "people pleaser". Someone who uses the motivation of fulfilling the assumed expectations of others as a prime motivating force. I think this is very different than being selfless, generous or sacrificial for others. It is more about getting approval from others by means of performance.
I personally know a lot about this flaw.

I like making some people happy.
But I have learned making most people happy is simply too hard to do.
So I pick and choose whom to please and when to do so.
At 63 I am older then a lot of people on this thread.
BTC making me millions is nice if it ever does.
But I value a lot of other things in life more than millions or even billions in BTC.
