Several quick thoughts:
No kidding. What's worse, it will likely be more than that. I've been self-insured since I started my first business in 1985. Insurance went up each year a little faster than inflation, but when "Obamacare" kicked in, it went through the roof. Both my wife and I have been perfectly healthy, but just before we went on Medicare two years ago, our insurance plus concierge fees (to be able to even have a doctor) went over $30,000 for one year ($2,500/month). This is more than double what it was in 2008, before this (un)
Affordable Health Care Act was enacted.
I am not a fan.
Even on Medicare, we're still paying over $10,000/year.
Second, talbm's list is amazingly good. I've run three companies and then spent a decade consulting with Internet startups. I can't add anything to what he wrote.
Finally, whether or not you do set up your own food truck, you should most definitely watch this great film about a chef who got fed up cooking for someone else and decided to do just what you're contemplating: start cooking from a food truck. The movie is a really fun two hours. You'll recognize quite a few of the actors. Here's the trailer (the food truck shows up at about the 1:30 mark):
The name of the movie is
Chef.
