A man's character is his fate.

A man is what he wills himself to be.

It is certainly true that whatever a man may do or say, the most significant thing about him is what he thinks; and significant also is how he came to think it, why he continued to think it, or, if he did not continue, what the influences were which caused him to change his mind.

A man's fate is his own temper.

Man is what he wills himself to be.

See how he cowers and sneaks, how vaguely all the day he fears, not being immortal nor divine, but the slave and prisoner of his own opinion of himself, a fame won by his own deeds. Public opinion is a weak tyrant compared with our own private opinion.

What a man thinks of himself, that it is which determines, or rather indicates, his fate.

Man is not fully conditioned and determined but rather determines himself whether he gives in to conditions or stands up to them. In other words, man is ultimately self-determining. Man does not simply exist but always decides what his existence will be, what he will become in the next moment.

When a man's position in life depends upon his having a certain opinion, that's the opinion he will have.

Man is what he believes.

A man is but the product of his thoughts. What he thinks, he becomes.

Man is nothing else but what he makes of himself.

"ethos anthropoi daimon - "A man's character is his fate.

A man is literally what he thinks, his character being the complete sum of all his thoughts.

That which a man continually thinks about determines his actions in times of opportunity and stress. I will know what you are if you tell me what you think about when you don't have to think.
