It is the people who can do nothing who find nothing to do and the secret to happiness in this world is not only to be useful but to be forever elevating one's uses.

Shall I give you my recipe for happiness? I find everything useful and nothing indispensable. I find everything wonderful and nothing miraculous. I reverence the body. I avoid first causes like the plague.

I have no problems with private schools. I graduated from one and so did my mother. Private schools are useful and we often use public funds to pay for their infrastructures and other common needs.

The knowledge of languages was very useful. I have a university degree in foreign languages and literature.

Economics is extremely useful as a form of employment for economists.
