Early success is a terrible teacher. You're essentially being rewarded for a lack of preparation, so when you find yourself in a situation where you must prepare, you can't do it. You don't know how.

Chris Hadfield

Embrace failure. Never never quit. Get very comfortable with that uneasy feeling of going against the grain and trying something new. It will constantly take you places you never thought you could go. This has been my mantra for years. I always remember I won't do things right on the first try. So failure is mandatory for success!

Terry Crews

If you always put limits on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.

Bruce Lee

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self.

Ernest Hemingway

Go to the gym, don't even work out. Just GO. Because the habit of going to the gym is more important than the work out. Because it doesn't matter what you do. You can have fun - but as long as you're having fun, you continue to do it.

Terry Crews

Decide in your heart of hearts what really excites and challenges you, and start moving your life in that direction. Every decision you make, from what you eat to what you do with your time tonight, turns you into who you are tomorrow, and the day after that. Look at who you want to be, and start sculpting yourself into that person. You may not get exactly where you thought you'd be, but you will be doing things that suit you in a profession you believe in. Don't let life randomly kick you into the adult you don't want to become.

Chris Hadfield

Being grateful is the bridge between the world of nightmares and the world where we are free to say no. It's the bridge between the world of delusions and the world of creativity. It's the power that brings death back to life, the power that turns poverty to wealth and anger to compassion.

James Altucher

I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. 26 times I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.

Michael Jordan

Don't count the days. Make the days count.

Muhammad Ali

We suffer not from the events in our lives but from our judgment about them!

Epictetus

Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do. So throw off the bowlines, sail away from safe harbor, catch the trade winds in your sails. Explore, Dream, Discover.

Mark Twain

If you start thinking that only your biggest and shiniest moments count, you're setting yourself up to feel like a failure most of the time. Personally, I'd rather feel good most of the time, so to me, everything counts: the small moments, the medium ones, the successes that make the papers and also the ones that no one knows about but me.

Chris Hadfield

“The only truly safe thing you can do is to try over and over again. To go for it, to get rejected, to repeat, to strive, to wish. Without rejection there is no frontier, there is no passion, and there is no magic.

James Altucher

Ultimately, leadership is not about glorious crowning acts. It's about keeping your team focused on a goal and motivated to do their best to achieve it, especially when the stakes are high and the consequences really matter. It is about laying the groundwork for others' success, and then standing back and letting them shine.
