Not sure if I agree completely. I've seen people regret giving their life to the service of others and not noticing they were not living their own life until too late.
The way I read it was: don't hoard, make others happy.
It does not mean I should live a miserable life in hope that someone, whom I'm giving to, will recognize it.
The wisdom can escape you if you take what's written literally letter for letter, as if you're a computer.
I'm married to a nurse, and I know a lot of people on the field. I'm constantly amazed how they are wired to take care of others before themselves.
one is doing something for others, the other is sharing what you have.
