Through a long and painful process, I've learned that happiness is an inside job - not based on anything or anyone in the outer material world. I've become a different and better person - not perfect, but still a work in progress.

A lot of hard work is hidden behind nice things.

In football, everything is possible, from the moment you work and you believe in your qualities.

With hard work and effort, you can achieve anything.

With hard work and dedication, anything is possible.

Being an astronaut is a wonderful career. I feel very privileged. But what I really hope for young people is that they find a career they're passionate about, something that's challenging and worthwhile.

The harder you work... and visualize something, the luckier you get.

No person who is enthusiastic about his work has anything to fear from life.

The only way to enjoy anything in this life is to earn it first.

For me, every day is a new thing. I approach each project with a new insecurity, almost like the first project I ever did. And I get the sweats. I go in and start working, I'm not sure where I'm going. If I knew where I was going I wouldn't do it.

Nothing is work unless you'd rather be doing something else.

There's something to be said in favor of working in isolation in the real world.

Can anything be sadder than work left unfinished? Yes, work never begun.

It's like Forrest Gump said, 'Life is like a box of chocolates.' Your career is like a box of chocolates - you never know what you're going to get. But everything you get is going to teach you something along the way and make you the person you are today. That's the exciting part - it's an adventure in itself.

The more I want to get something done, the less I call it work.

Instead of being critical of people in authority over you and envious of their position, be happy you're not responsible for everything they have to do. Instead of piling on complaints, thank them for what they do. Overwhelm them with encouragement and appreciation!

One thing I never want to be accused of is not working.

All things are difficult before they are easy.

Luck? I don't know anything about luck. I've never banked on it and I'm afraid of people who do. Luck to me is something else: Hard work - and realizing what is opportunity and what isn't.

Management is nothing more than motivating other people.

Working hard and working smart sometimes can be two different things.

Nothing ever comes to one, that is worth having, except as a result of hard work.

The only thing that overcomes hard luck is hard work.

Organizing is what you do before you do something, so that when you do it, it is not all mixed up.
