1) Know that this is a completely normal feeling, especially in more individualistic/atomized cultures where status competitions are more pronounced.
2) YOU have the answer to your question, it's just a matter of uncovering it. I would recommend writing/journaling. Spend a lot of quiet time exploring your thoughts, and asking probing questions of yourself. "Why do I want to do more? What do I think will happen once I do those projects? How will that feel? etc." If I were to guess, some of the story may be around the drive for increased social status. But I can only speculate.
3) Remember you are a human with a physical body/needs, stay attuned to it. Move your body, exercise, go outside and breathe in fresh air, eat well, play with your kids/family/friends. Working remote and on a computer is incredibly convenient, but sometimes it removes our attention from the physical world.
4) Be BIG in your very SMALL world, forget about trying to be BIG in the BIG world - If there's any part of you that thinks about how what you accomplish looks to others and how it'll reflect on your relative status/legacy, I'd recommend making your world smaller/more local. The internet/media shows us what outliers are doing all around the world at all times, and it can make whatever we're doing feel so miniscule in comparison. You'll never 'Win' the global status games, nobody can really. Focus on your very small part of the world, your family, your friends, your local community. How can you be the best parent/spouse/neighbor to them? Being good here has the highest ROI once you've let go of the global status games (which you'll be forced to let go of at some point). For creative projects - what will bring YOU or those closest to you joy? Forget about thinking about how anything you build will scale broadly/globally.
