You never know what motivates you.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
It's always too early to quit.
Only the educated are free.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
If you think you can do it, you can.
Things do not happen. Things are made to happen.
If you're going through hell, keep going.
If a politician murders his mother, the first response of the press or of his opponents will likely be not that it was a terrible thing to do, but rather that in a statement made six years before he had gone on record as being opposed to matricide.
