Truth be told, not everyone is suitable to be a business owner. I once started a wine business two years after I graduated from college, with money I borrowed from my parents. Unfornately it ended up as a failure and I have learned great lessons from that experience. Looking back, I actually don't regret on that "experiment" although I lost much money. Now I am living a comfortable life and keep all lessons in mind. It is just best to know who you are and what you really need.
I believe in 2 things, people who are born with skills, and people who are not born with skills but those people want to learn to become someone with skills. I may agree that not everyone is suitable to be a business owner, (I mean skills) but if you study hard then everyone gets the same opportunity to be successful as a businessman. As I said at the beginning, not being born with such skills does not mean closing the opportunity to be able to have these skills.
