Let me tell you of some ways, that you can use, to do your drawing easy, there are a number of different ways, you can do this, one of them is, by keeping your drawing to a minimum.
Perhaps we can call this, the minimalist KISS method, Keep It Simple Stupid-KISS.
Minimalism, is an art form in its own right, just in case you didn’t know but in my brain, I most often consider, that less is more and without getting into any deep philosophy, on this, I often feel that simple is best. The process used, for all drawing is, construction through sequential building blocks, with each being a step, to the next and so on, to completion.
When shading a drawing, you can keep it to a minimum, by using, the white of the paper, as much as possible and only shading, the darker areas, so as to reduce the amount of work needed, in doing all of the detail. This can be very effective, producing some nice drawings, that are in a style called chiaroscuro, where there are strong contrasts, between light and dark. These where often practiced, by drawing statues and plaster busts, which would be, very light in tone because they would often, be white in color or very near white, making it easy, to keep the shading, to a minimum, only emphasizing the darkest tones.
To make drawing easy, we need to reduce, the amount of steps we take, to get to an end result, so we can do this, in a number of ways. Reduce the drawing, down to use a minimum number of marks, in order to make the drawing more simple. This can be accomplished by making line drawings and examples of this, can be seen in, cartoon type drawings, Bart Simpson, Mickey Mouse characters, are just a couple but there are probably, thousands of others, meaning that simple is just as legitimate, as the complicated.
Another method is tracing because it will reduce, the time spent, on doing a construction drawing and reduce the drawing, to only be made up, of simple lines. This can be a big saving, depending on how much you know or understand about it and your ability, because somebody, who is good at drawing free hand, by sight drawing, can sometimes, draw faster, than they can trace, some drawings. Tracing is also, a very good tool for learning to draw and is, I consider, largely undervalued, under exposed and practiced by many, if not all professionals because when, you do drawing, as a job of work, time is money.
The key to drawing easy is, to keep it simple, less is more because if you consistently draw, in ways that are simple, the harder ones, get easier, as well.
