Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
After a storm comes a calm.
Leap, and the net will appear.
The wise does at once what the fool does at last.
Be thine own palace, or the world's thy jail.
Only the educated are free.
Quality is not an act, it is a habit.
It's always too early to quit.
If you can dream it, you can do it.
That's something I learned in art school. I studied graphic design in Germany, and my professor emphasized the responsibility that designers and illustrators have towards the people they create things for.
