I can, therefore I am.

Quality is not an act, it is a habit.

You never know what motivates you.

Go for it now. The future is promised to no one.

Things do not happen. Things are made to happen.

If you're going through hell, keep going.

The wise does at once what the fool does at last.

If you think you can do it, you can.

Know or listen to those who know.
