As somebody who also tries to constantly become better at drawing, I've noticed drawing faces has become slightly better for me. Why? Because I keep trying again and again. Something fun to do is to draw your friends, and at least you have some motivation to show them and they might enjoy it. You can also try to draw your favorite actors, actresses, etc. I keep trying to draw Mao Inoue, since she's incredibly cute.
My biggest advice is to take formal classes. Often times, teachers introduce you to different mediums, whether it's charcoal, plain pencil, or countless other mediums, you'll want to find the one you enjoy the most. For example, I hate painting because I feel I have no control, and I hate charcoal because it's a mess. I hope to take some art classes that help me draw people, since I like drawing people the most.
And to end, I just want to reiterate what I previously said, as well as others. That is to practice, practice, and practice some more. Find some relaxing music (if you want some Japanese music I recommend Halcali or Kat McDowell) to listen to while drawing. Even podcasts are nice to keep you focused to some extent. Have fun with it, and try to impress other people since positive feedback is a great form of motivation to get better.
