Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
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.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
