“I can’t draw!” Yes, well, even proficient artists feel like that, at times. There always seems another level to rise to, and never enough practice to get you up there.
Like most things art, though, it’s all about patience and regularity. Practice isn’t a temporary condition for students, it’s a lifetime habit. Whatever you cultivate will yield fruit, and that’s not just for real life stuff, it includes compelling abstract work. But to sidestep frustration with our progress—and lack of it—in drawing any particular subject, it’s about two main things.
First, simple tenacity. Drawing is the foundation of all other visual art, and it feeds into everything else if you do it regularly to keep in practice. It’s like working out, you’ll never notice changes day-to-day, but every so often you notice you’re suddenly better—or fitter—than a few weeks ago, months ago, years ago.
Second, kindness. Not in general—but do that, too—but to ourselves. Be kind to you and try to avoid beating yourself up for any perceived lack of progress. There’s no end point, so there’s no race or rush, it’s just something you do. And it can be anything, not necessarily a high concept or grand scene. Simple lines. Circles. Cups. Leaves. Hills. Buildings. Faces. Figures. All worthy subjects along the way. Just the habit of working, as usual, is the most important thing.
Then, don’t stop.
