The problem with starting your own company and line of products is that you would need investors to help the start up. This requires good PR and communication skills. This is the reason why I see some of my classmates with brilliant ideas get shut down. They are either too shy or lack the confidence to step up.
So much talent and potential is wasted on having second thoughts.
The brilliant idea is then replaced by an okay idea promoted by a "smooth-talker." If there is a way to help our brilliant introverted friends out there, I think it is upon us to help out and be a part of the potential advancement of mankind.
