Yes alcohol can be abused. But just because you choose to get shitfaced doesn't mean you don't know how to have fun the "real" way. It also doesn't mean you're an alcoholic. And just because you don't drink, doesn't mean you're the outcast.
Your post would have been a lot more meaningful if you neglected the part about the alcohol altogether. I think what's inspiring is that you chose to go down a different path and it led to amazing things in your life. Drinking is irrelevant and takes away from the good message you try to convey.
