I am looking for a lot of men who have an infinite capacity to not know what can't be done.

The period is now arrived, in which either they or we must change our sentiments, or one or both must fall.

We always like those who admire us; we do not always like those whom we admire.

If you know the enemy and know yourself you need not fear the results of a hundred battles.

Benevolence, righteousness, propriety, and knowledge are not infused into us from without.

All that is important in this moment is movement. Make the movement vital and worth living. Do not let it slip away unnoticed and unused.

Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined or the insect, as well for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.

The more I study science the more I believe in God.

The shoe that fits one person pinches another; there is no recipe for living that suits all cases. Each of us carries his own life-form—an indeterminable form which cannot be superseded by any other.

The creation of a thousand forests is in one acorn.

Do not think that what is hard for you to master is humanly impossible; but if a thing is humanly possible, consider it to be within your reach.

It's the possibility of having a dream come true that makes life interesting.

Man can learn nothing unless he proceeds from the known to the unknown.

You better live your best and act your best and think your best today, for today is the sure preparation for tomorrow and all the other tomorrows that follow.
