I feel like this needs to be explained. You guys are conflating a lot of different things. It's normal, people do that all the time when they don't fully grasp the purpose behind certain strategies/exercises/techniques/etc but it's not quite what you think.
At the end of the day, *how* you draw your marks is up to you. It's not that there is no right nor wrong, it's that *you* decide what you're aiming for, and whether you hit it or not determines whether it was correct. If you want to draw a line, and the only reason you use chicken scratch is because you're physically incapable of drawing it in one go, then you never really made a conscious choice that "I am going to be sketchy with this mark". You just did what you knew you could do, not what you necessarily wanted to do.>>4690623
Courses like drawabox push you to focus on thinking first, and then executing your marks with a single stroke, because it builds up good habits. It forces you to plan before you act, not to go with your gut instinct because you don't actually HAVE any instincts worth a damn as a beginner. Those instincts are things you develop by thinking first. As you get better, the amount of time you need between wanting to put a mark down and putting it down (that is, the planning and care in between) diminishes, and so when you need to draw quickly, you need to do rapid iterations on designs and whatnot, you'll be better equipped to do that.
Competent artists don't "chicken scratch". They may draw in a way that is visually similar to chicken scratch, but it's not chicken scratch because that's not the literal only thing they can physically do. When they make a mark up with individual strokes, they make those marks flow into one another, and those marks still individually serve their own purposes. They're not doing what beginners do, just building a bridge out of short sticks from point A to point B.
