If you can't explain it simply, you don't understand it well enough.

We are what we repeatedly do. Excellence (Areté) then, is not an act, but a habit.

All life is an experiment. The more experiments you make, the better.

You can do anything, but not everything.

Real generosity toward the future consists in giving all to what is present.

There is nothing so useless as doing efficiently that which should not be done at all.

Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.

The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.

When we seek to discover the best in others, we somehow bring out the best in ourselves.

Whatever you can do or dream you can, begin it. Boldness has genius, power and magic in it. Begin it now.  

Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree.

Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.

You are the average of the five people you spend the most time with.

Nothing will benefit human health and increase the chances for survival of life on earth as much as the evolution to a vegetarian diet.

Be yourself; everyone else is already taken.

If we did all the things we are capable of doing, we would literally astound ourselves.

Don't judge each day by the harvest you reap but by the seeds that you plant.

If we can see the path laid out for us, there is a good chance it is not our path; it is probably someone else's we have substituted for our own.

Most of us have two lives. The life we live, and the unlived life within us. Between the two stands resistance.

No enterprise can exist for itself alone. It ministers to some great need, it performs to some great service not for itself, but for others...or failing therein, it ceases to be possible and ceases to exist.

Be yourself. The world worships the original.

Do your job and demand your compensation, but in that order.

Each man is questioned by life; and he can only answer to life by answering for his own life; to life he can only respond by being responsible.

Success is peace of mind which is a direct result of self-satisfaction in knowing that you did your best to become the best that you are capable of becoming.

You have to reject one expression of the band before you get to the next expression. And in between you have nothing. You have to risk it all.

You must never confuse faith that you will prevail in the end with the discipline to confront the most brutal facts of your current reality, whatever they might be.

99% is a bitch; 100% is a breeze.

There are only two mistakes one can make along the road to truth; not going all the way, and not starting.
