A few additional points, as someone who spent several years taking courses in drawing in college.
- Don't get caught on the nerd treadmill of tools-before-effort. You can draw with whatever is in your junk drawer. You can draw well with $40 of different hardness pencils and kneaded erasers from an art supply store. Beyond that is a waste.
- As parent said, practice practice practice. Which means finding time to practice. For which a portable sketchbook and basic portable kit is a huge help.
- (Disagree with parent, here) Find someone(s) who won't hold back to judge your work. You need someone who can say (and who you can handle hearing say) "This part sucks." Because you need to hear that, and work on it, until it doesn't. In professional training this is "jury." One-directional courses (them to you) aren't going to help here, as you need feedback.
- Start drawing from life, because you have an infinite supply of content that all obeys the laws we assume to be true (perspective, lighting, gravity, etc). And you'll be able to tell if it looks correct or not.
- Drawing from pictures can help "freeze" a moment. This is especially important for outdoor light and shadow, as otherwise the sun angle will change while you're working.
- Learn to draw what you see, not a representation of what you see. This means don't draw a symbol of a house, but draw the house in front of you. Focusing on details and working through them methodically helps avoid symbolism. E.g. draw that line, or that corner, not the whole thing.
- Draw with intent: every drawing should have a concrete goal when you're learning. It doesn't have to include everything. Consider including or excluding lighting and shadow, which takes a huge amount of time to get right. E.g. circular mass studies, perspective line work, proportion. Think about what you want in this drawing, and then practice only that.
- Find an art buddy or community. This is the opposite of jury! ;) Where you go when you're feeling like your work sucks and you'll never be good, and they'll remind you of all the ways you're awesome.
Edit: 110% agree with sibling comment re: grids for proportion work, when you're learning. Inability to maintain proportion across the work is a huge source of beginner "doesn't look right"ness. Eventually you'll internalize it, and get better at relative proportion with other things in the drawing, but they're a good crutch to start with.
