Question: What's your business experience? I've worked in big companies and small startup companies.
A healthy degree of pessimism is essential in any sort of business. ...
Well this thread is not about me and my comments were originally directed to help the OP in answering his question. However, since you asked and since it might give some insight to the OP, I can give some basic information.
I'm not a business minded person in the strict sense. I've always focused on learning and technology and I'm basically best described as a researcher. I was able to take my Ph.D. work and use it as the basis to launch a start-up technology company. Over 8 years, with investors and managers, brought in at opportune times, the company was successful and was sold to a large corporation with myself, partners and some investors doing very well in the end.
I've seen all of the issues (you've described above) first hand. Also, when I began, many friends and family members questioned my choice, sounding very negative about the prospects of being successful in business, as you did. The success I had was the result of a hard fought (although enjoyable) battle. It is the type of battle that is never fought by a pessimist.
Of course the question then becomes. "What if you had lost the battle?". My answer would be that the education, experience and the adventure is priceless; hence, it is a no-lose situation. And, I would have been more prepared for the next attempt, with a much higher chance of success. In the end, if you don't give up, you eventually succeed.
Note that even with success, more is possible. I currently work as a research scientist, in industry, in a field unrelated to my previous work. I chose this new field (renewable energy) because it is interesting to me and it will become an explosive market in the future. Once my expertise is developed enough and once I have the right critical mass of innovative ideas and once the timing is right with the economy and the targeted markets, I'll do it again. I will then have two advantages that I didn't have before - (1) a track record of success to help convince investors to put money in, and (2) no need for investors.
I want to be clear that I'm not claiming to be Bill Gates or anything like that, but I'm basically an engineer that has made about as much as a well established medical doctor with a successful practice. This is my basic point. I'm asking the OP to not compare a physicist working at a university or in industry to a medical doctor with his own successful practice. The comparison should more accurately (even if imprecise, or even crude) be made as follows:
doctor doing research in industry => physicist doing research in industry
doctor working at a hospital => physics professor at a university
doctor owning his own practice => physicist owning a consulting firm or a technology company
Hopefully, this will help get this thread back on track.
