The path will be different for everyone.... I can imagine that is not what you want to hear, but it's true. One person may do it with internet business while the next apartment buildings and the next self-storage. I would suggest you spend a little time reading and browsing - and see what excites you.
Then, learn all you can in your area and start looking for your opportunity.
I would add one thing.... I partnered with my mom and her husband on a project. Their stress level was much higher then mine was, and I believe it was due to their proximity to retirement age. If the project went/goes south, I still have years to rebuild... they, on the other hand would struggle. Be sure you have taken and honest and thorough look at your tolerance to risk.
