Not everyone is cut out to be

a plumber, or an LSAT tutor, or a lawyer.

Somehow people fall into their places or become jobless.

In addition, a tutor can have group lessons. But for a plumber to have a "group lesson", he must???

There are many ways to make a living. If you ask a homeless guy why he chooses his way of life, he may say: I like it!

Plumber or LSAT tutor, is just different ways of living. Personal choice.
