NoOneNearMe

Hi, I've been a software engineer for about 4 years now, and I feel like I can't make any useful piece of software. I usually get stuck and take a while to make any meaningful progress.

For example; I tried making some programs around terrain generation in OpenGL, and was able to get something nice. However, it seems that there are so many people that did the same thing but way better. I saw a video of someone make a Minecraft terrain in 48 hours. And just today, saw a High-school student make a procedurally generated terrain for their game, which is way better than mine.

Seeing the successes of all these people brings me so much anxiety and prevents me from moving forward with projects I want to do. Does anyone else feel the same way, or know if anyway to get out of this mental trap?
