If you think you can do it, you can.
Always desire to learn something useful.
It's always too early to quit.
Leap, and the net will appear.
Who seeks shall find.
You never know what motivates you.
Only the educated are free.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
Well done is better than well said.
The reason people find it so hard to be happy is that they always see the past better than it was, the present worse than it is, and the future less resolved than it will be.
