Be gentle to all and stern with yourself.

It's always too early to quit.

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

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

If you can dream it, you can do it.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.

Well done is better than well said.

If you're going through hell, keep going.
