When learning a new craft or subject, a lot of times there's a entry level barrier people must go through. It's hard, frustrating, and feels like you're not making any progress. If given enough time, you will eventually git gud and actually enjoy it.
While other people may seem smarter or more creative, don't worry about how other people progress compared to you. Focus on your own improvement and don't give up, because you can just be at the point where it just starts to "click" and you understand and appreciate it.
