Joe,

I think the better way to get started is with some kind of idea related to an industry that you are already very familiar with. You said that you have worked for 40 years. Let's say for example that you have spent many many years working in the bike industry. Then, building some kind of device that benefits the bikers would be your best bet. Because you have so many years working for this industry you will probably know very important people related to the bike business, and things will be a lot easier for you.

I am sure that if cncmachineguy comes up with a clever idea to use with CNC machines he could make tons of money . Well, you got my idea.
