I like some of your thoughts, Al. Being humble is good too -but underestimating your skills is not. I believe your experiences will take you far in life.
I've also dedicated myself to slow growth, and I want to keep things as simple as possible as a solo entrepreneur. Sometimes it can get lonely, but you can do things your way.
There is no hurry, and you need to love what you do. In that way, you can enjoy the process, not just the goal.
