" You would think that this would be whether the entrepreneur’s idea is actually a good one. But finding a good idea is apparently not all that hard. Finding an entrepreneur who can execute a good idea is a different matter entirely. One needs a person who can take an idea from proposal to reality, work the long hours, build a team, handle the pressures and setbacks, manage technical and people problems alike, and stick with the effort for years on end without getting distracted or going insane. Such people are rare and extremely hard to spot. "
