My dear friend, clear your mind of cant.
I'm sorry I wrote you such a long letter; I didn't have time to write a short one.
The present is theirs; the future, for which I really worked, is mine.
Courage isn't having the strength to go on - it is going on when you don't have strength.
The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly.
Too much sanity may be madness - and the maddest of all is to see life as it is and not as it should be.
The past cannot be changed. The future is yet in your power.
We cannot direct the wind, but we can adjust the sails.
When we see men of a contrary character, we should turn inwards and examine ourselves.
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.
What lies behind us and what lies before us are tiny matters compared to what lies within us.
If we want a free and peaceful world, if we want to make the deserts bloom and man grow to greater dignity as a human being-we can do it.
Don't hit at all if it is honorably possible to avoid hitting; but never hit soft!
Happiness depends more on the inward disposition of mind than on outward circumstances.
If you paint in your mind a picture of bright and happy expectations, you put yourself into a condition conducive to your goal.
If you can't you must, and if you must you can.
You can't live a perfect day until you do something for someone who will never be able to repay you.
Life is 10 percent what happens to you and ninety percent how you respond to it.
The question isn't who is going to let me; it's who is going to stop me.
You yourself, as much as anybody in the entire universe, deserve your love and affection.
It marks a big step in your development when you come to realize that other people can help you do a better job than you could do alone.
