This is true in life as well. There are many ideas, things which we could probably do. But just because something (interesting or profitable) is possible, that doesn't mean we should do it or even spend much time pondering it. For those of us who see problems and solutions _everywhere_, this is a surpreme challenge. Or for those who "ramp up" quickly to new things, everything seems possible. Consequently, any good idea not pursued seems like a lost opportunity. It may be! But it may also be a distraction from doing something which is also important and already in motion.
