I can relate to your past situations as I'm sure many here can. Many of us have had things happen in our past that haunts us. I know that I have.
MY main motivation in doing this is to do something fun. After 40+ years of either working for someone or being in business, or both at the same time, I wanted something different.
This is something that I can do that doesn't require physical assets if I choose not to. A brick building and equipment is a huge investment. I've owned a night club, a transportation company, and a vending company , so I know about physical assets.
This is much more fun, but it takes just as much prowess and intelligence as running any other business.
Good luck to you in the future my friend.
