Be gentle to all and stern with yourself.
If you think you can do it, you can.
The wise does at once what the fool does at last.
You never know what motivates you.
After a storm comes a calm.
Expect problems and eat them for breakfast.
Go for it now. The future is promised to no one.
Well done is better than well said.
Never complain and never explain.
The most effective way to do it, is to do it.
Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
