When your brain tells you are done, you are only 40% done.

If you haven't done something yet, and you want to do it, start now!

I feel like I'd invested so much in the physical side of my life: running marathons - I brought a SEAL into my house - I have a trainer. But I've invested very little on the inner work, and in a world of distractions, I felt like to have the whole picture, I really had to spend a little time alone and work on being present.

I realized that so much of our precious time is taken up by obligations that we don't even really need.

The answer is that I do want to climb Everest, but I don't want to go to Everest. I don't want to be cold. I can't take the time. It's just not practical.

I do a workout every morning in which I purposefully try to make myself uncomfortable. It sets me up for the rest of the day by reminding me that I can choose to be OK in the midst of tough challenges.

I like the concept of 'have your cake and eat it, too.'

As an entrepreneur, you are constantly playing in uncharted territory, and sometimes things don't work out. That doesn't mean you failed; it just means you may be off course.

Anytime you take someone's money, that puts enormous pressure. But I think if you want the most reward, you have to take the most risk.

At a young age, I realized that getting letters is exciting.

It's better to set a big goal to try and then fail than to never set a goal in the first place.

One thing I thought of, I call it By Sea, By Land, By Foot. It'd be a 100-mile paddle, a 100-mile run, and a 100-mile bike, back-to-back-to-back. But I don't want to end up in the hospital.

I'm a New Yorker, man. I'm a Knicks fan.

The concept of getting out of my routine, mixing it up, and pushing myself to live the grittiest life is something I try to incorporate every day.

If you can't do the little things right, you will never do the big things right.

Any time I meet someone or learn about someone that's really interesting or inspiring to me or has a story that really resonates with me, I just cold call them, and I try to meet him or her.

Before I left for American University, my mother told me to sign up for everything I could: to take advantage of everything from on-campus lectures to sports and social events to the amazing D.C. culture.

I used to delay doing stuff that I just didn't want to deal with - things like putting the garden hose away properly or doing the dishes right after dinner. Now I have this little voice in my head that says, 'I know you don't want to do this, but just do it anyway.' In other words, there's far less stuff that I put off until tomorrow.

I was networking every day from 21 to 28 years old. I sent 10 letters a day, which means I reached out to 3,000 people in a year.

I was a kiddie pool attendant, and I was a white rapper. That's not going to get you a job on Wall Street.

So many of us live our lives on autopilot. We wake up, go to work, have dinner, go to sleep... repeat.

I'm an extremist. If I go to a sneaker store, I buy 20 pairs of sneakers, not one.

It's easy to let yourself down - it's tough to let other people down.

Almost all of my business flights are commercial, not private.

I have a crazy background in music, both as a performer and writer.

When we first started Marquis Jet back in 2001, one of our first goals was to try to break into the Hollywood marketplace. We thought it was a good way to help build brand credibility and attract new customers by word of mouth.

A lot people who hear that 'Go New York Go' assume that I must be black.

P Street in D.C. is one of the worst areas in the city. Some of the things I saw, the things I experienced, the things we came through, really gave me a whole new perspective on life.

To me, the thing is, through good or bad, if you're a Knicks fan, you're down with the Knicks, and that's the bottom line.

I'm creature of habit.

I've run 350 days a year for 20-plus years, and never once have I listened to music. It's a time for me to think, listen to natural sounds, be outside.
