The clichéd image of entrepreneurs coming up with an idea, laboring feverishly to perfect it, and delivering their creation to the market full-born is not what usually happens. The much more typical path is that they come up with an idea. They take a small step toward implementation to see if anyone is interested, and if it looks like there is potential market acceptance, they take another step forward. If they don’t get the reaction they want, they regroup and then take another step in a different direction.
In other words, they
Learn (from that action) and
Build (off that learning) and Act again.
