10X principle

If you want to be really great at something—whether you have a startup, work in an investment firm, or are involved in any company—it's very important that whatever you do is 10 times better, 10 times cheaper, or 10 times faster, ideally all three, than the competition or existing solutions.

I almost use the economic concept of additionality, which means that you're doing something that wouldn't happen unless you're actually doing it. The more you can do things like that, the bigger impact you have. It's about doing things that people might not think are possible.
