It's always too early to quit.
Be gentle to all and stern with yourself.
You never know what motivates you.
Wherever you are - be all there.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
Well done is better than well said.
The most effective way to do it, is to do it.
Only the educated are free.
Teaching man his relatively small sphere in the creation, it also encourages him by its lessons of the unity of Nature and shows him that his power of comprehension allies him with the great intelligence over-reaching all.
