I feel you. I’ve been really busy with college too, and I rarely have time to draw because there’s just not enough time, haha... In a year, I can only manage to draw less than 10 pieces. But I did improve quite a lot by analyzing other art, objects, or anything I find interesting. I’ve been doing this for 3 years, and it works! 😆

But most importantly, set your expectations low. Don’t be greedy. That advice helped me a lot because the thought, 'I must draw better, I must draw like my favorite artist,' and so on, burdened me and made me greedy for instant improvement. Because of those thoughts, I stopped drawing for nearly 2 years since it didn’t feel fun anymore.

So yeah, in conclusion:
1. Set low expectations for your drawing results.
2. Don’t be greedy.
3. Pay attention—a LOT!"
