Would You Still Build Your Product If It Didn't Make Money?

During COVID-19 times, when most of us were locked in our homes; I built several products. Most of them were tiny products that I could build in 2 weeks.

These were simple web apps; for example a web-app to quickly send a thank you or appreciation to anyone, without them requiring to download any app.

Of course - the product never made any money.

Over the next few months; I lost the will to keep building it. People were using it; but it wasn't growing exponentially.

Eventually, I stopped building it - and killed it.

Looking back, maybe I should have kept building it and let it grow at its own pace.

I want to know - would you keep building your product if it didn't make any money? Let me know why.
