Never complain and never explain.
After a storm comes a calm.
Only the educated are free.
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.
If you're going through hell, keep going.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
What you do today can improve all your tomorrows.
As man sows, so shall he reap. In works of fiction, such men are sometimes converted. More often, in real life, they do not change their natures until they are converted into dust.
There's time enough, but none to spare.
