I run my own company, that sells Lenovo products to small business. But truth is, I don't make very much doing it. But it's helping me make connections into the corporate world. I make must of my money with "Human Directionals". The guys in the road spinning a sign trying to get your attention. Also small well thought out investments in the stock market. Such as 1,6xx shares in Ford I bought two years ago and sold off recently...
But I am starting my first year in school this month, but I will still be taking the same approach.
