I experience that plenty as well. I think one of the biggest lessons that we have to learn in this life is that there will always be someone better (and lesser) than us. We can have the biggest ambitions but whether by skill or circumstance we are limited in execution. My art ideas regularly end up vastly different once completed. Of course, there are things we can still do. We can practice and hone our craft. For your work, you can recruit people who can fill up resource gaps in your project. You can also get yourself a mentor and learn from their experience. But even if you become an excellent artist, you'll still be plagued with your own insecurities, a sense you're not where you ought to be. And that's alright. Because it means that there's still something worth reaching for. But at the same time, you would want to stop feeling insecure so you can get down to the work at hand and make things. First of all, try to avoid looking at too many artworks on the internet. Sure they're beautiful, but the pathway that gifts inspiration is the same road taken by our insecurities. The same goes for Likes in social media. Second, do the work. Play your fav podcast/audiobook/music and get down to business. We are what we pay attention to, after all. You can apply that to your work and life. Just get going, learn along the way, and make something, however imperfect. But because you put in the work, you got the experience to be better than when you started. And from there you'll start having bigger dreams and ambitions but this time, you'll be working from a better place. It's important that you have these ambitions because they signal a deeper yearning within yourself, as Robert Browning aptly put: "Ah, but a man's reach should exceed his grasp, Or what's a heaven for?" In the short story, "The Middle Years", the MC notes that he spent his entire life learning his art, so a second life ought to be expected to put it all into practice. But we only have this life. So the MC tells another character what's left for us: "We work in the dark — we do what we can — we give what we have. Our doubt is our passion and our passion is our task. The rest is the madness of art." Take the first steps, be kind to yourself, and learn to work in the dark. Good luck anon. In life and in art, I'll be cheering for you.
