Be contemporary. Have impact. Strive for it. Be of the world. Move it. Be bold, don’t hold back. Then the moment you think you’ve been bold, be bolder. We are all alive today, ever so briefly here now, not then, not ago, not in some dreamworld of a hypothetical future. Whatever you do, you must make it contemporary. Make it matter now. You must give us a new path to tread, even if it carries the footfalls of old soles. You must not be immune to the weird urgency of today.

We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. Most of your actions are based on incomplete knowledge and you really don’t know what it is all about, or what the purpose of the world is, or know a great deal of other things.

Following your bliss is useless. People are passionate about a lot of stupid things. It’s not a great mantra. Meaning, I think, comes from doing a full accounting of your limitations and assets, your passions and your weaknesses, your belief system and your fears, and then rubbing up against the things that cause you to panic, like an allergy skin scratch test, and find out what your reactions are. Once you figure out how you can contribute to the greater good, once you’re able even to define that, you take that information and pour yourself into one direction. Regardless of discomfort or regrets or what-ifs. That does not fit on a T-shirt.

Occasionally you’ll find yourself desperately searching for something that inspires you. Only you’ll be looking for the wrong thing in the wrong places, because what you’re drawn to is the thing that makes noise, or moves, or flashes. Sometimes the thing you should be looking for to feel inspired is the thing that you aren’t noticing, the thing that’s not at all flashy.

When you love your job you don’t gossip about the personal failings of others. You talk about their successes, because you’re happy for them – and because you’re happy with yourself. When you love your job it’s like peeling an onion. There are always more layers to discover and explore. When you hate your job it’s also like peeling an onion – but all you discover are more tears.

What you should prepare for is mess. Life’s a mess. You are not entitled to expect anything from it. Life is not fair. Everything does not balance out in the end. Life happens, and you have no control over it. Good and bad things happen to you day by day, hour by hour, moment by moment. 
Don’t expect anything. Erase all life expectancies. Just live. Your life is over as of today. At this point in time, you have grown as tall as you will ever be, you are physically the fittest you will ever be in your entire life and you are probably looking the best that you will ever look. This is as good as it gets. It is all downhill from here. Or up. No one knows.

Put yourself into unusual situations. Put yourself in unusual cultures, where you don’t belong. Put yourself amongst people who you don’t normally hang out with. Out of your comfort zone.

1. Condition your mind. Train yourself to think positive thoughts while avoiding negative thoughts.

2. Condition your body.It takes physical energy to take action.  Get your food and exercise budget in place and follow it like a business plan.

3. Avoid negative people. They drain your energy and waste your time, so hanging with them is like shooting yourself in the foot.

4. Seek out the similarly motivated. Their positive energy will rub off on you and you can imitate their success strategies.

5. Have goals–but remain flexible.No plan should be cast in concrete, lest it become more important than achieving the goal.

6. Act with a higher purpose.Any activity or action that doesn’t serve your higher goal is wasted effort—and should be avoided.

7. Take responsibility for your own results.If you blame (or credit) luck, fate or divine intervention, you’ll always have an excuse.

8. Stretch past your limits on a daily basis. Walking the old, familiar paths is how you grow old. Stretching makes you grow and evolve.

9. Don’t wait for perfection; do it now!Perfectionists are the losers in the game of life.  Strive for excellence rather than the unachievable.

10. Celebrate your failures. Your most important lessons in life will come from what you don’t achieve. Take time to understand where you fell short.

11. Don’t take success too seriously. Success can breed tomorrow’s failure if you use it as an excuse to become complacent.

12. Avoid weak goals.  Goals are the soul of achievement, so never begin them with “I’ll try …”  Always start with “I will” or “I must.”

13. Treat inaction as the only real failure.  If you don’t take action, you fail by default and can’t even learn from the experience.

14. Think before you speak.  Keep silent rather than express something that doesn’t serve your purpose.

Consider the knowledge you already have — the things you really know you can do. They are the things you have done over and over; practiced them so often that they became second nature. Every normal person knows how to walk and talk. But he could never have acquired this knowledge without practice. For the young child can’t do the things that are easy to older people without first doing them over and over and over.
Most of us quit on the first or second attempt. But the man who is really going to be educated, who intends toknow, is going to stay with it until it is done. Practice!
