Whatever you have, someone else has a better version of it. Whatever you have, someone else would kill to have it themselves.
The only way to step outside of the cycle is to start comparing yourself to yourself. Whatever it is that you do, be better at it. Be the best at it. Don't focus on improving, focus on straight up dominating. It's counter intuitive, but the best way to get to the next level is to acknowledge that you aren't very good right now. It's difficult, most successful people refuse to admit any kind of fault or regret. That's fine for the merely successful. But you should be trying to become godlike. When you aspire to that level, how much money other people raise or how often they appear in the press won't matter to you any more than the business of ants on the ground. If you want to transcend envy[0], you must transcend yourself and your current level of ambition.
It doesn't matter what anyone else is doing, or what people think of them. It doesn't matter what anyone thinks of you. Show the world something wonderful and amazing, do things that people didn't think were possible. Solve a real problem for millions of people, or just impress yourself with how cool what you've made is. Do whatever is necessary to make your name shine, whatever the cost. Everything else will take care of itself.
[0] pedantry: "envy" is the desire for what others have, "jealousy" is the fear that someone else will take what you have.
