I’m about being the best.

Wherever the invitation of men or your own occasions lead you, speak the very truth, as your life and conscience teach it, and cheer the waiting, fainting hearts of men with new hope and new revelation.

Life is to be lived. If you have to support yourself, you had bloody well better find some way that is going to be interesting. And you don’t do that by sitting around.

I think it’s healthy for a person to be nervous. It means you care – that you work hard and want to give a great performance. You just have to channel that nervous energy into the show.

The man who goes alone can start today; but he who travels with another must wait till that other is ready.

I think sometimes the best training is to rest.

Every action has a consequence. It may be good for strengthening. And I have no doubt that lifting a lot of weights can get you stronger. I just don’t know if lifting stronger weights can keep you healthy, or it can keep you doing your job better, especially for a pro athlete.

You fail only if you stop writing.

You just can’t beat the person who never gives up.

How to gain, how to keep, how to recover happiness is in fact for most men at all times the secret motive of all they do, and of all they are willing to endure.

I’m just an individual who doesn’t feel that I need to have somebody qualify my work in any particular way. I’m working for me.

Why should I be studying for a future that soon may not exist?

On the mountains of truth you can never climb in vain: either you will reach a point higher up today, or you will be training your powers so that you will be able to climb higher tomorrow.

Get up tomorrow early in the morning, and earlier than you did today, and do the best that you can. Always stay near me, for tomorrow I will have much to do and more than I ever had, and tomorrow blood will leave my body above the breast.

Of course, I do everything for money.

There are more people dying of malaria than any specific cancer.

I’m not very ambitious at all.

I never got into training to be an All-Ireland boxing champ or to win a belt. At the start, I just got into it to learn how to defend myself when I got into situations.
