You never know what motivates you.
Well done is better than well said.
By failing to prepare, you are preparing to fail.
Begin to be now what you will be hereafter.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
Go for it now. The future is promised to no one.
It's always too early to quit.
Leap, and the net will appear.
If you're going through hell, keep going.
Eventually, I believe, current attempts to understand the mind by analogy with man-made computers that can perform superbly some of the same external tasks as conscious beings will be recognized as a gigantic waste of time.
