If I had to distill my advice about how to operate down to only two words, I’d pick focus and intensity. These words seem to really apply to the best founders I know.

They are relentlessly focused on their product and growth. They don’t try to do everything—in fact, they say no a lot (this is hard because the sort of people that start companies are the sort of people that like doing new things.)

As a general rule, don’t let your company start doing the next thing until you’ve dominated the first thing. No great company I know of started doing multiple things at once—they start with a lot of conviction about one thing, and see it all the way through. You can do far fewer things than you think. A very, very common cause of startup death is doing too many of the wrong things. Prioritization is critical and hard. (Equally important to setting the company’s priorities is setting your own tactical priorities. What I’ve found works best for me personally is a pen-and-paper list for each day with ~3 major tasks and ~30 minor ones, and an annual to-do list of overall goals.)

While great founders don’t do many big projects, they do whatever they do very intensely. They get things done very quickly. They are decisive, which is hard when you’re running a startup—you will get a lot of conflicting advice, both because there are multiple ways to do things and because there’s a lot of bad advice out there. Great founders listen to all of the advice and then quickly make their own decisions.

Please note that this doesn’t mean doing everything intensely—that’s impossible. You have to pick the right things. As Paul Buchheit says, find ways to get 90% of the value with 10% of the effort. The market doesn’t care how hard you work—it only cares if you do the right things.

It’s very hard to be both obsessed with product quality and move very quickly. But it’s one of the most obvious tells of a great founder.
I have never, not once, seen a slow-moving founder be really successful.

You are not different from other startups. You still have to stay focused and move fast. Companies building rockets and nuclear reactors still manage to do this. All failing companies have a pet explanation for why they are different and don’t have to move fast.
When you find something that works, keep going. Don’t get distracted and do something else. Don’t take your foot off the gas.

Don’t get caught up in early success—you didn’t get off to a promising start by going to lots of networking events and speaking on lots of panels. Startup …
