Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
Begin to be now what you will be hereafter.
What you do today can improve all your tomorrows.
Go for it now. The future is promised to no one.
If you think you can do it, you can.
Either you run the day or the day runs you.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.
Math is sometimes called the science of patterns.
A lot of the high-level sports are really in your mind.
