Never complain and never explain.
Expect problems and eat them for breakfast.
If you're going through hell, keep going.
Be kind whenever possible. It is always possible.
Either you run the day or the day runs you.
What you do today can improve all your tomorrows.
It's always too early to quit.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
Things do not happen. Things are made to happen.
Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
