Teach the art of business
People are perpetually in business for themselves, allocating their resources. Analyze life's transactions, big and small, with your children: Is it worth it, say, to order the $13 steak at dinner?
Don't compete, create
Teaching a kid to rate himself against others doesn't create an entrepreneur; it creates a company man. It's healthier to trade with someone than defeat him--and easier, too.
Have your kids record their hobbies and interests on the left side of a T-chart. Then have them derive a business idea from each. Repeat for family and friends' interests.
Positive attitude is everything
Too often rejection rules the markets. Teach them to never take rejection personally. Show them that with distance comes perspective and that one can always learn from mistakes.
Don't go overboard
Taking this effort too seriously--making it a chore--is a sure way to turn your kid off business entirely. Too many entrepreneurs try to recreate themselves in their child.
