I would like to start a business and leave the work-for-pay paradigm of a salary and/or consulting. For the last 20 years, I've switched between salaried employment and independent consulting. Technically consulting is my own business but I'm looking for something that is not limited by the time I can put in. I am good with technology and enjoy it so I'd like leverage that into some sort of business. I'm not trying to start the next Amazon or Uber. I have some capital and could take time off work. I'm just short of ideas. Google helps me find tons of articles about tiny businesses and things to start up on a couple hundred dollars but that's not what I'm looking for.
Does anyone have any ideas on where I can get inspiration? When I was in my 20s, I had plenty of inspiration but no capital to do anything about it. Now I'm in the opposite boat. I'm looking to do some research and don't quite know where to start. Books would be fine but I need some specific recommendations because I'm about 5 books in and they're all focusing on the shoot big thing and I don't need that much money.
My primary motivation for this is to bring life back into my career. The first ten years were great because I was climbing and having a lot of successes. Now I'm "there" but after 10 years, I need to move on. It's not that it's terrible, but I'm pretty bored and looking for a new challenge. The business option is really the only way to step up from here. Salary-wise, I can't really go up without going into management and that is not appealing to me at all. Technology-wise, I'm in one of the top 10 high-demand, high-pay jobs so learning a new technology would just be going sideways into the same thing.
Thanks for any suggestions or perhaps a recommendation of another place I could post this question.
