I am turning old. Approaching 36, to be exact. In 10 years, I will be square in the middle of mid-life, and hopefully not in a crisis. I used to, and still do think a lot about products, startups, business, etc. 10 years ago, everything seemed possible and easy and profitable. Now, with experience working in industry, interacting with people, knowing what I know, the way I evaluate an idea has drastically changed. I am more skeptical, conservative in my estimates, cautious in growth prospects. I still think myself to be innovative. But reality has grounded me.
