Do you still have the work from when you did it last time? All the boxes?

I think it would be a good oppertunity for you to compare where you are now to where you were a few months ago by redoing a little now and seeing if they look similar or better. Maybe even asking others to evaluate. If last time was retained at all, then chances are you'll perform somewhat better this time. If not, then- well, yeah, start over.

If I were you, I'd reread the lessons in Lesson 0, and then redo Lesson 1, becuase if you didn't do the 50% rule last time, I feel that you didn't really understand why it was so important AND necessary. Its really the one huge part of this entire program that makes people grow, its not optional for a reason. Its not just about your mental health, its about "playing with your skills". People who are most skilled at something, can play with those skills. Mathmaticians can make games out of equations, coders can do personal coding challenges, arcobats can parkour. Its the idea that- your skills are most mature, and most adept, when you know how to play with them. You'll not only be capble of applying skills in ways you didn't know where possible, but playfullness produces mastery far beyond what a class can teach. Playing with your skills makes you a master at them- that 50% rule isn't as simple as "keeping you mentally well" its doing half the job of teaching you.

Its incredibly important, I think, that you reread things and listen to the videos and absorb them. Don't speed through with the mindset of "I need this done"- do the tasks with a mindset that disregards time all together. If you are putting deadlines on when these skills need to be mastered, chances are, you aren't going to master them well. Mastery can't be made in haste, it has to be made slowly. I used to think drawing was something your hands would just do and that I didn't have to think through it, it would just happen. But, later I realized- the mind is doing almost all the work. Being delibrate, focused, concentrated, slow, and patient every time you sit down to draw- helps you master the skills better than anything else. If you are worried about "getting it done" - you'll be missing out on half of the training these exercises provide.

Adjust your mindset, and if you chose to do them all again, I think you'll gain from it, if nothing else, you may gain the patience to exist in the moment with what work you have in front of you, without feeling the "urgency" to escape it. Its a mindfullness technique, and it will serve you the rest of your life, even outside of drawing. Getting to that point- will help you never burn out again.

That's just my thoughts. Please feel free to do what works for you, and if another's advice is better, take it instead.

Good luck, you got this.

Review the lesson material in full starting from Lesson 0 to the point where you left off. Then do a week of only focusing on warmups, no new homework, then resume where you left off (assuming you still have your old boxes - if not, you'll still need to turn in 250 so you'll have to start that over).
