I believe we are humans and we are able to learn nearly anything. Sure, your physical and mental will have limits but many of them are temporary and can be broken. I also never graduated high school, but I have taught myself enough to employ my self for many years using tools like the internet. It was my education after college that really makes me money, things I thought would be valuable and enjoyable so I researched and figured it out. It takes hours of dedication to learn something new but if you decide to do it then I believe you can figure it out. All we do is learn.
