Then be an accountant or a banker. This is the riskiest of all industries. Especially 1099 contract work. You will never know if you have a job from month to month let alone year to year. These companies are being bought out and aquired and sold daily. And that is just the company, I haven't even touched on getting and retaining business from Doctors. You never know if or when the doctor's cousin, brother or even son is going to get a job and he switches all business to his relative. Or if there is a recall or an injuntion involving your best selling product.
Heres a good rule of thumb... If there is potential to make a lot of money, there has to be high risk. Are you willing to take that risk or not?
As far as 1099 being the starting point, not so much. I would suggest you take a W2 position until you hit the point where it is holding you back from making more money. Also remember when you are a 1099, you are responsible for double the employment taxes and withholdings, insurance, allowances, entertainment, and so on. Make sure you consider all expenses of running your own business before you deside to go 1099.
