How does it feel to learn drawing when you enjoy drawing? Do

Like learning.

Sometimes.

Sometimes.

Tedious exercises are always tedious. . . If a person were to be doing the exercises and it wasn't tedious, they are either doing them incorrectly or shouldn't be doing them.

It becomes more fun when you notice results. Maybe if, when drawing those boxes you begin drawing at a different angle which makes them line up better. Stuff like that helps, but just mindlessly doing exercises is mostly just draining.
