Evan Williams posts some correspondence from Naveed Ahmed about being an entrepreneur:

I think to be a successful entrepreneur only 3 things matter:

1. A clear vision of where your company is going.
2. Genuine desire and passion to create amazingly great products/services.
3. Strong conviction that your product/service is going to make a positive difference in your customer’s life.

Evan likes it – so do I. I think it captures the essence of what my aim was with joining Marc at NETaccounts (I don’t speak for Marc, but I believe he feels this way too).
