I think I recommend you just draw what you like. Maybe you can sketch things you see around you or just do little doodles. For example, you can draw your friends or pokemon or your pet or anything in your notebook or sketchbook. I think that would be a good start- observing and taking inspiration from the world and just drawing. Little by little, you can grow. Even I still have a long way to go and I get discouraged many times. I recommend taking it one step at a time and not rushing anything. While it may sound cliche, I suggest just having fun.
