I'm 29 and thought about quitting and doing my own and was talked out of it by my older peers at my corporate job. I was about 24 for then. In hindsight it was by far one of my regrettable decisions. I see products and ideas being created that were all in my personal incubator. Not to mention they are all profitable. So I say this, if you have internet, time & a mind anything is possible. Good luck on your ventures. I'm sure success will find you.
People tried to talk me out of it too. They all thought I was crazy (maybe I am). But I know I would regret not seizing the opportunity. Thank you for your comment.
Really its out of comfort and fear of the unknown. I do freelance development and it scratches the itch I have to do interesting work for now. I also have decided to wait until I stumble upon a great idea. Really I'm to the point now I'm just working for healthcare. Meaning I'm paid well but spend nada.
