Problems are not stop signs, they are guidelines.
I can, therefore I am.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
Who seeks shall find.
If you've got a talent, protect it.
The most effective way to do it, is to do it.
After a storm comes a calm.
If you think you can do it, you can.
