Be kind whenever possible. It is always possible.
It's always too early to quit.
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.
You never know what motivates you.
Things do not happen. Things are made to happen.
What you do today can improve all your tomorrows.
The most effective way to do it, is to do it.
Never complain and never explain.
If the highest things are unknowable, then the highest capacity or virtue of man cannot be theoretical wisdom.
