The biggest lesson Jim Cramer has taught his children is to be self-reliant with money. Cramer has grown children in their 20s and 30s.

He expects his children to live within their means even though he has a lot of money. That means he won't invest on their behalf. Cramer doesn't like giving money to his own kids and having them invest it. He doesn't want his kids to get a handout from him, instead he wants them to make their own investment decisions.

He says it won't mean anything if it's not theirs.

Jim Cramer is with his family.

Jim Cramer is the author of "Jim Cramer's Mad Money."

Cramer's daughter is a counselor that works with troubled youth. Cramer says that she makes a very low income but still invests her money even if it is a few shares at a time.

She owns her own money. He says that she has done well, but he doesn't want to give too much. He wants his children to be given enough so that they can do anything, but not enough that they can't.

The wife of Jim Cramer is with her two children.
