The mistake I see people make it _not_ ending their career out of narcissism, pride, ego, etc.

I am not a religious person but it is good to remember you will die. You should have some better stuff to put on your tombstone than your job title.

People aren't going to care who you were in 100 years and people aren't going to remember you in 1000 years. Your tombstone will crumble in the dirt.

Spend time with people you love, spend time with your family and friends. Find meaning without economic strings attached.
