No sense being pessimistic... it wouldn't work anyway
I know that's a very silly quote, but somehow it seems extremely appropriate for entrepreneurial ventures. Every direction we turn we find endless reasons for being pessimistic, if not cynical. If you really are an entrepreneur, somhow you manage to get past all of the mines in the minefield. Humor is a key aspect of our survival. But, it's also very true that pessimism simply doesn't work for entrepreneurs.
