Every man gotta right to decide his own destiny

A man has not every thing to do, but something; and because he cannot do every thing, it is not necessary that he should do something wrong.

Whatever each man can separately do, without trespassing upon others, he has a right to do for himself; and he has a right to a fair portion of all which society, with all its combinations of skill and force, can do in his favor.

A man's gotta do what a man's gotta do

When a man comes through
He must do what he's supposed to do
When a man comes through.
He can't do what everyone expects him to.

Every man is working out his destiny in his own way and nobody can be of any help except by being kind, generous, and patient.

Every man must bear his own burden.

A man must know his limitations.

As for a future life, every man must judge for himself between conflicting vague probabilities.

A man can do only what he can do. But if he does that each day he can sleep at night and do it again the next day.

A man does what he must - in spite of personal consequences, in spite of obstacles and dangers and pressures - and that is the basis of all human morality.

There are no buts, my son. True there are degrees of honor — but one man can have only one code. Do what you like. It's your choice. Some things a man must decide for himself. Sometimes you have to adapt to circumstances. But for the love of God guard yourself and your conscience — no one else will — and know that a bad decision at the right time can destroy you far more surely than any bullet!

The only clue to what man can do is what he has done.

Every man has his own reason for every deed. Usually it is selfish.
