Never complain and never explain.

It's always too early to quit.

Always desire to learn something useful.

Be kind whenever possible. It is always possible.

If you're going through hell, keep going.

Go for it now. The future is promised to no one.

If you think you can do it, you can.

The wise does at once what the fool does at last.

Be thine own palace, or the world's thy jail.
