If you think you can do it, you can.
To know oneself, one should assert oneself.
After a storm comes a calm.
To be a good loser is to learn how to win.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
Leap, and the net will appear.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
Be thankful for problems. If they were less difficult, someone with less ability might have your job.
