Experience with entrepreneurs

I personally have been around one particular entrepreneur my whole life, Rex Helms. He personally started selling car stereos out of the trunk of his car in Cullman and when he acquired a Radio shack dealer store through debt that was owed to him he turned it into a thriving business. He has been in business for many many years throughout different store locations and move after move but the business is still going strong. I first met Rex Helms when I was younger and had to go to work with my dad on days that school was out because of weather and the such and then I did not learn to much about him but today I work for him and learn many things from his experience, things such as how to keep inventory and check inventory as well as how much time and commitment it takes to being an entrepreneur. I am impressed by his knowledge and try to learn from him any chance i get.
