I "made it" in three different businesses. First was a weekly shopper newspaper 30 years ago. I sold out at a wonderful price after only five years.
In 1988 I opened a night club and it was probably the most successful in town for seven years. Doing all my own entertainment was the key!
I later owned a golf driving range and club-making business. It was just starting to make it when I lost the lease on the land.
I've also been pretty successful as an entertainer for the past 30 years.
The pitfalls are paying your own retirement, insurance, etc., but it CAN be done if you want to do it badly enough.
