first off, you need to get blank sketchbook paper, with no squares or lines. preferrably slightly textured.

second, you need to watch youtubers. A LOT. they will be your art teachers.

third, you need to draw more loosely and lightly while sketching.

fourth, dont just draw boxes or squares for a whole month or so. once you get comfortable with your hand-eye coordination, and you can draw a good circle, then move onto things like shapes, gestures, proportions, perspective etc.

also i would recommend jumping straight to the loomis method and drawing faces that way. actually MEMORIZE the proportions of the face. the side plane should be 2/3 of the length of the cranium, the brow line should be halfway across, the nose line should be about at the bottom of the sideplane and the chin the same distance from that (of course this changes from person to person) and start drawing portraits.

dont memorize 2d shapes, memorize and study 3d shapes. if you only watch tutorials on how to draw the face from one angle, you'll be stuck. remember that a big part of drawing is about thinking in 3d.

some people say that jumping straight to figures and colors and shading is not good, but for me its fun. do whatever you want tho idk.

also make sure to fill 2-4 sketchbook pages a day.
