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.
Well done is better than well said.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Be kind whenever possible. It is always possible.
If you're going through hell, keep going.
It's always too early to quit.
Things do not happen. Things are made to happen.
