Not a car related business, but a tattoo shop here. I am on year 5 on my own and wouldnt have it any other way. After working for some really great guy and some not so great ones, I enjoy the stability of running things myself. Knowing that my boss is not going to be dead the next day is nice...(happened to my 2 times)...and a third just turned into a junky. At first costs were low, rent, not a lot of overhead....then you start to make some money and buy more things/upgrade. We bought our building 2 years ago and we are basically using it as our retirement savings instead of investing in the stock market or some other venture. So at the beginning I was content making "x" ammount of money, and now I HAVE to make "x + x" just to stay afloat. I do have things to show for it though...well, at least we will in 30 years! Just dont get more than you need and be gready...while at the same time pushing yourself and your worth so that you can retire some day. Oh, and the IRS is no joke. Pay that shit on time or the penalties are unreal.
