You haven't written for such a long time, you must have lost your kung fu. The painting will definitely be worse if you try again, but it doesn't matter if you practice your hands first. Although I haven't been in contact for more than ten years, time can accumulate some experience, which is better than not learning at all!
Since you want to pick it up again, come on! Usually draw something whenever and wherever you have a pen, which is actually quite effective. Draw more sketches, not necessarily sketches of people, but also small objects around you ~
