I would say domain knowledge and experience. I've been in my industry for long enough to spot situations where my work will have disproportionate impact. The longer I am in this industry, the more knowledge, contacts and followers I have, so I can be very effective at building things, getting them validated, and finding users for it.
I’m not in the industry or part of a company yet—I’m still on the younger side.
I’ve had many ideas and I work on them, but nothing really takes off. I keep coming back to the same question: is this worth it? Especially because every idea I have, I run it by my friends—they love it, I build it, they don’t use it, and I’m left with a dead project, a half-empty wallet, and goals I could have pushed further with if I hadn't taken up the project.
Bit of an ad because I am trying my best to get my product out there everywhere.

You can tell because the product answers OP's question.
