An interesting observation from bootstrapper.com:
Now, most entrepreneurs usually start with a single idea and can think of nothing but that during their first company. However, somewhere along the lines, after about 2 years of running a company, just about every entrepreneur I know starts coming up with dozens of ideas for new companies. It is like there is some hidden tipping point where every hard driven entrepreneur becomes an idea junkie.
We need idea junkies more than ever right now! Even in the toughest economic times there are real opportunities in the market.
