The important thing is to strive towards a goal which is not immediately visible. That goal is not the concern of the mind, but of the spirit.

You can't hit a target you cannot see, and you cannot see a target you do not have.

What you get by achieving your goals is not as important as what you become by achieving your goals.

If you were born without wings, do nothing to prevent them from growing.

Aim higher in case you fall short.

Far away there in the sunshine are my highest aspirations. I may not reach them, but I can look up and see their beauty, believe in them, and try to follow where they lead.

Nothing interferes with my concentration. You could put on an orgy in my office and I wouldn't look up. Well, maybe once.

The real pleasure of one's life is the devotion to a great objective of one's consideration.

If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them.

No one knows what he can do until he tries.

The distance is nothing; it is only the first step that is difficult.

From a certain point onward there is no longer any turning back. That is the point that must be reached.

Perhaps when we find ourselves wanting everything, it is because we are dangerously close to wanting nothing.
