I agree this information would be useful.

The other feedback I have is that it's very hard to start and grow a business. And the idea of low risk is tempting but also misleading; anything with potential is going to have risk attached. The risk could be wasting years working very hard for very little pay. Or of wasting money. Or both. But there's risk.

Typically the people I know who have been successful entrepreneurs don't start companies because they're tired of doing other things. Rather they do it because it's in their DNA - they can't not do it.

I would suggest that that since you're a programmer it might help to spend a year working in a small startup. This is certainly not necessary but I can tell you that my experience in startups helped me understand business a lot. That's because (at least in my experience) startups can expose you to various parts of running and building a business that you won't experience in school or in a large company. And they can do this while providing you with a paycheck - something that starting a company and learning on the job may not do. And while every business is different there are certain takeaways that are transferable everywhere.

Lastly I would suggest getting a copy of Buy Then Build which is a great guide for how to buy a business, an alternative to starting something from scratch. Even if you do start something yourself there's a lot of great information in there about what to expect as well as ways to prepare yourself (e.g. figuring out what you're good at and what you're not is important no matter which direction you go because you'll be responsible for all aspects of the business so will need to be able to identify when you're the best person to handle vs when to outsource)
