Short YouTube talk by Scott Duffy presenting the "hammers and nails" metaphor for a common entrepreneurial mistake: trying to do too many things at once. Duffy contrasts single-focus (one hammer, one nail) with multi-tasking (multiple hammers/nails), argues single-focus increases the odds of success despite early misses, and prescribes: concentrate on one thing, perfect it, then move to the next.

The biggest mistake that entrepreneurs make is focusing on too many things at once. And I call this hammers and nails syndrome. And here's what I mean. Let's say I gave you one hammer and one nail and your job is simple. All you have to do is take that hammer back and drive that people that nail into a piece of wood. Like, really nail that one business. Now, the odds are you may miss the first time, you may miss the second, but eventually I'm going to bet. I'm going to bet on you. I'm going to bet that you're going to nail it. So let's say I give you two hammers and two nails. You've got a problem. Who's going to hold the nails? So let's say you find somebody crazy enough to do it. You have to take a hammer in each hand, you have to bring them both back at the same time, and you have to strike at the same time. And think about that. The odds are you may miss the first, the second, the third time. You may never get it right. Let's say I give you 10 hammers and 10 nails. You get the point? You see, the biggest mistake entrepreneurs make is they focus on too many things at once. And so what I say is this, don't focus on everything. Focus on one thing. Really nail that one thing and then move on to the next.
