More or less part of the point I was making. However using once again the example of a relationship, the equivalent would be staying in a relationship that is going nowhere (which doesn't even mean it's "bad" just that you know it won't end up where you want it to be for some reason..). As a result you are "tied up" and less able to iterate and take chances with meeting someone who might be the right person. In other words you have to be free and available in order to explore dating a new person and I simply feel that while there is a point to staying on your "bad" idea in order to learn and apply the knowledge elsewhere, time is not unlimited and being able to work on even finding or testing a potential new idea is priceless.
When the internet came along I was involved in a manufacturing startup which I put about a year worth of time and energy into (buying equipment, travel to shows etc.) After the operation was all setup I got the idea to put in a T-1 line and try the new "internet" thing. In a short time (a few months) it became apparent that the new idea was much better than the old idea which would have taken much much more time. I sold off everything and focused solely on the new idea rather than split my time between two ideas. (And back in early 1996 btw it wasn't crystal clear that the internet was going to be what it is today so it was taking somewhat of a gamble since the other idea was proven and the market was mature..)
