Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
If you think you can do it, you can.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
If you can dream it, you can do it.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Could I have but a line a century hence crediting a contribution to the advance of peace, I would yield every honor which has been accorded by war.
