Einstein

Intellectual growth should commence at birth and only cease at death.
Only a life lived for others is a life worthwhile.

Deadline is the only way to live for others.
How could I say I live for others if I do not do anything for them. If I do anything for them, I need deadlines to deliver it.
If you can not explain it simply you do not understand it well enough.
Logic is natural.

The value of a man should be seen in what he gives not in what he is able to receive.
If you want to live a happy life, tie it to a goal, not to people or things.
Deadline is used for it.

The only way to live for others: have deadlines. Do some work.
