Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
If you think you can do it, you can.
The wise does at once what the fool does at last.
Wherever you are - be all there.
Either you run the day or the day runs you.
Things do not happen. Things are made to happen.
I think America has more than enough maturity and intelligence to start exercising its world leadership responsibly.
