The point? What ever it is in life you wish to achieve don't let anything stop you. Whether you have a formal education or not matters very little. The only ingredient that is the most needed in accomplishing anything is ganas; that is, the desire to do it.
So if you want to build a house, take the first step in that direction and don't look back. Eventually you will have built that house. If you want to design a new computer, maybe it will take you decades but I assure you that if you devote your time and energy to that purpose you will come out victoriously showcasing your new creation.
Whatever it is, just go for it. Don't think that in order to make your dreams come true you have to go to college for years and years so that you may attain a paper that says that you have the ability to do something. You already have that ability in you. We all do.
