And there are people doing business on the internet who apparently fail to realize that the web is a constantly changing landscape and that one of the secrets to continued success is to stay fluid and capable of moving at a moments notice. You're intentionally, emphatically eliminating opportunities before you've even had a chance to test them. "They don't conform to my non-bending schedule so I'll never use them." That's absurd. Rearrange your schedule to accomodate them. Stay flexible. Maintain the ability to implement new changes and exploit new opportunities within minutes if need be. Trust me, you'll get a lot further that way.
