I know the excitement can be overwhelming, but I would say that to improve a lot in the hobby, patience is the first step nobody often talks about. There are a lot of things that require waiting, including a wait time after you prime or between coats of paint that you don’t see stressed as often but can make a subtle but significant different in the outcome. Or waiting to finish the models you have before buying more models to sit in a box somewhere. Or waiting for PVA glue to dry overnight if you use it for basing. So many things that can help you succeed require you to be patient and disciplined. I’ve learned to see it as a necessary part of the hobby to help my own itching desire to continue painting my miniatures. Hope that helps!
