If you think you can do it, you can.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
If you can dream it, you can do it.
The dog that trots about finds a bone.
To be a good loser is to learn how to win.
It's always too early to quit.
Go for it now. The future is promised to no one.
Only the educated are free.
You never know what motivates you.
I don't really trust a sane person.
