I have been in business for myself for over 25 years. I think the real challenge to being in business is the ability and desire to solve problems. No matter the nature of your business, pitfalls and problems with always pop up. Its how you handle them that makes you successful or not. If you are thinking about going into business for yourself, I would suggest you sit down with someone that will be honest with you to discuss the negitives, we all can list the positives.
Personally, I wouldn't have it any other way.
