Be thine own palace, or the world's thy jail.
The wise does at once what the fool does at last.
Never complain and never explain.
If you've got a talent, protect it.
Begin to be now what you will be hereafter.
If you think you can do it, you can.
If you can dream it, you can do it.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
To know oneself, one should assert oneself.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
