This week, I caught up with a founder friend. His company is early-stage, and he’s at an inflection point. They have early customers, and revenue is growing at a moderate clip. But he has a nagging feeling that his market isn’t the ideal market to build a company in. There are lots of competitors, and prices are going down quickly, which is pressuring his margins. His customers could build a comparable solution in-house, but they use his solution because it’s cheaper, for now, than building it themselves. Translation: his customers will build something in-house if they start spending too much with his company. Last, his customers view his solution as a nice-to-have, not a must-have.

The founder is trying to figure out whether he should keep pushing through with his current product. He doesn’t want to feel like he’s giving up too early.

I thought about Felix Dennis and his book How to Get Rich as we chatted. The book is about how to succeed as an entrepreneur, which leads to wealth—it’s not just about how to get rich. One thing Dennis shared was that entrepreneurs need to be persistent. They need to have conviction that they’re right and will be proven right (hopefully shortly). Conversely, though, Dennis said that entrepreneurs shouldn’t be stubborn, which means you’re persisting even when there’s plenty of evidence that you’re wrong or that you shouldn’t persist. In a post about this book (see here), I shared the following:

Acknowledging a mistake and realizing a new plan is needed are signs of clear thinking and help focus your persistence on the right activities. The most successful people I know are persistent but also rational and clear thinkers.

I’m not sure what my friend will do, but I shared with him that giving up on something doesn’t mean you aren’t persistent if the data and the market are telling you it isn’t working. It’s an opportunity to redirect your energy and persist toward the right thing.

My takeaway from this chat and Dennis’s book is that I want to be persistent but not stubborn. I want to think rationally in choosing what to work on and be persistent about the right things.
