Problems are not stop signs, they are guidelines.

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

If you're going through hell, keep going.

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

If you think you can do it, you can.

You never know what motivates you.

What you do today can improve all your tomorrows.

It's always too early to quit.

To know oneself, one should assert oneself.
