Never complain and never explain.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
If you can dream it, you can do it.
Be kind whenever possible. It is always possible.
It's always too early to quit.
Always desire to learn something useful.
Only the educated are free.
Well done is better than well said.
By failing to prepare, you are preparing to fail.
Bad things do happen in the world, like war, natural disasters, disease. But out of those situations always arise stories of ordinary people doing extraordinary things.
