Problems are not stop signs, they are guidelines.
You never know what motivates you.
To be a good loser is to learn how to win.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
After a storm comes a calm.
Always desire to learn something useful.
Leap, and the net will appear.
A serious and good philosophical work could be written consisting entirely of jokes.
