I remember, as a boy of 17 years of age, this was a fascinating thing for me: how we human beings breathe out carbon dioxide into the air, the leaves of plants pick this carbon dioxide up, and the plant gives off oxygen, which we can breathe in and keep our life going.

I've worked on films where the budgets are almost limitless and you're in trailers that are bigger than a hotel room. You're taken care of and the food is amazing, the quality of the job is amazing and then you work on smaller things but it never dictates my happiness or my willingness to go to work.

Happiness depends upon ourselves.

I know nothing worth the living for but usefulness and the service of my fellow-creatures. The only object I pursue is to increase, as far as lies in my power, the quantity of their knowledge and goodness and happiness.

All beautiful and noble qualities have been united in me... I shall be the fruit which will leave eternal vitality behind even after its decay. How great must be your joy, therefore, to have given birth to me.
