You know what they say: If at first you don't succeed, f**k it.

Burn every memory that does not help you grow. Destruction, too, can be necessary.

If at first you don't succeed, try, try again. Then quit. No use being a damn fool about it.

At the end of the day, you may as well try and fail than not try at all.

If at first you don't succeed...run.

You may be disappointed if you fail, but you are doomed if you don't try.

You may be disappointed if you fail, but you will be doomed if you don’t try.

Trust none of what you hear, half of what you read, most of what you see.

if you can’t prove something wrong, you can’t really prove it right either.

You can’t destroy knowledge. You can stamp it under and burn it up and forbid it to be, but somewhere it will survive.

The only guarantee for failure is to stop trying

When I have tried and failed, I shall have failed.

Nothing ... will ever be attempted, if all possible objections must be first overcome.

Everyone must destroy their life. According to the way they do it, they're either triumphants or failures.
