Begin to be now what you will be hereafter.
The wise does at once what the fool does at last.
If you can dream it, you can do it.
Go for it now. The future is promised to no one.
Leap, and the net will appear.
Be gentle to all and stern with yourself.
Well done is better than well said.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.
