Don't buy into the 20-hours-a-day entrepreneur myth. You need to sleep 8 hours a day to have a focused mind.

Whenever things are good, I always worry about what could go wrong.

You can't make money without selling something real. You can't make something real without first imagination manifesting itself in your head. You can't have imagination without surrendering yourself to an idea that you want to create something of value to other human beings.

Become a beacon of enhancement, and then, when the night is gray, all of the boats will move towards you, bringing their bountiful riches.

Whether you're an entrepreneur, an employee, a student, a homemaker, a writer, it's time to start forgetting about all the ways the world has promised you safety and comfort.

If you introduce person A to person B, and then person B is able to solve a pain point in his life, then you just made a good connection.

My feeling, based on my own experience, is that aiming for grandiosity is the fastest route to failure.

I made so many mistakes in my first successful business I'm almost embarrassed to recount them.

When I give away a book for free, it gets my name out there. That has lifelong value for me that goes way beyond the few dollars I could maybe charge.

You can only make money doing what you love.

I love being honest and intimate with people. I love building community. I love emailing with readers.

Mistakes I've made in the past make me afraid to try new things in the future. I want to be perfect.

I can tell you this: Everything in my life that I am happy about it is the product of a huge mistake.

My grandfather was an illegal immigrant for the 60 or so years he was in the United States. I had another great-great-grandmother on my mom's side who snuck in in a suitcase.

America is a country of fighters. People who fought their way in and then continued fighting.

I keep track of my blog stats, Facebook subs, my Amazon rank, Twitter followers, Facebook likes per posts, my chess ranking. I get stressed when they all don't go up.

It's hard to know which stars in the sky will turn into black holes. And which ones will open up worm holes into entire new universes.

Read every sentence you write out loud. If it sounds boring, kill it.

A lot of times, people send me emails, and then I forget about them, or I never respond to them, or I respond to them weeks later.

Help is a conversation. If one side talks too much, the other side will get bored. So make sure you help back when you can.

When I was 22, I was thrown out of graduate school and then fired from three jobs in a row at higher and higher salaries where I saved nothing.

Buying coffee on the street instead of in a Starbucks is the poor man's way to get rich. In other words, you will never get rich by scratching out ten cents from your dollar.

Being a leader doesn't mean you are the guy who runs things.

Being a leader doesn't mean you created something or you did something great in the past or some other person has given you any kind of authority.

I always imagine a good leader is surrounded by people who call their mothers at the end of the day and tell them, 'Mom, you can't believe what I did today. Let me tell you about it.'

People unconsciously know when you are not listening to them. Then they say 'No' to you.

You can say no to people who make you feel bad about yourself. To people who backstab you or make you feel anxious in any way.

Life is better when your sinuses are clean, when your arteries are clean, and when your digestive tract is clean.

Nobody is more worthy of love in the entire universe than you. I wish I had reminded myself of that more.

Every tomorrow is determined by every today.

The universe wants us to have fun doing more than one thing in life. That's how it learns. You don't have one purpose in life. You have maybe 500 or so.

An out-and-out fast bowler is one of the great sights in cricket.

Partnerships are not just about bowling in tandem all the time. It all is about helping the other guy get in the right frame of mind.

What I try to do is improve as much as I can so I can be the best bowler I possibly can.

Milestones have never really meant a lot. They probably will mean more when I've finished playing and actually reflect on what I have achieved.

I've just enjoyed playing for England - it's an amazing job.

Part of the reason I fell in love with cricket was watching fast bowlers. They provide a sense of theatre with dramatic, ferocious spells and that applies as much in one-day cricket as in Tests.

For a fast bowler, not much stress goes through my body.

Lord's is such a special place and to get my first and now my 500th wickets here is something that will live with me for a long time.

I remember playing a Twenty20 game in Australia in 2007 and Matthew Hayden smacked one back at me. My head goes down as I follow through and as I looked up I just saw this white flash pass about an inch from the side of my head. If it had been a touch straighter I would not have had time to react and who knows what could have happened.

I am quite stingy when it comes to giving runs away.

I play a bit of golf, off a 12 handicap.

Growing up, my education about Test cricket came from dad's video of the 1981 Ashes series - and Ian Botham's incredible match at Headingley.

The time to think about personal achievement is at the end of your career.

A coach can help only so much. Out on the field you need a partner.

There's a fiercely competitive rivalry between myself and Virat Kohli - but also enormous mutual respect.

Instinctively I know the difference between general pain from bowling, and pain caused by a specific problem.

For me, what works is keeping training short but with high intensity and then recovering well. Physio, massage, icing, things like that.

A lot is made of the pink ball. But it is the same really. A good ball is a good ball, regardless of the colour. You might want to bowl a touch fuller with the pink ball when it is nipping around but generally a pink kookaburra behaves the same as a red kookaburra.

Test cricket tests your ability as a cricketer but also bring out your true character.
