I have deeply regretted that I did not proceed far enough at least to understand something of the great leading principles of mathematics, for men thus endowed seem to have an extra sense.

I know I'm probably much too late to try and apologize for my mistakes.

The true conquests, the only ones that cause no regret, are those made over ignorance.

MY greatest regret in life is that I never became the heavyweight boxing champion of the world.

Be yourself, be pleasant, play hard and have no regrets.

Tries to think that I'm just doing my own thing, but every time I look back it always really makes sense in that time.
