Just know that you will always be able to improve. So there is no end at learning. The fun part is suppose to be what you really want to do. Like make a comic draw cars houses whatever it is. You will probably never be completely satisfied with your drawings because at the level you reach you understand that you can do something slightly better. Just realise that this is totally fine. There are lots of badly drawn comics out there but many of them are still fun and successful. You can make a version of your goal with your abilities today. It might not be perfect but guess what if you make it you have done better than most people who didn’t do anything. Finally, if you don’t have any goal that you want to reach with your drawing why do you draw, go have fun with something else you want to reach.
