Problems are not stop signs, they are guidelines.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Well done is better than well said.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
Leap, and the net will appear.
Only the educated are free.
The most effective way to do it, is to do it.
Go for it now. The future is promised to no one.
If someday they say of me that in my work I have contributed something to the welfare and happiness of my fellow man, I shall be satisfied.
