If you think you can do it, you can.
If you're going through hell, keep going.
If you can dream it, you can do it.
To know oneself, one should assert oneself.
Wherever you are - be all there.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
After a storm comes a calm.
The wise does at once what the fool does at last.
I write in the morning from about eight till noon, and sometimes again a bit in the afternoon. In the morning I start off by going over what I had done the previous day, which my wife has happily typed up for me.
