A typical /beg/ trap is to take, say a portrait painting and to try to copy it. A /beg/ has a low attention span and an untrained eye, so after 30min/1h, he'll call it a day, and will have produce something absolutely horrendous, and would lose confidence and be unwilling to proceed further.
Instead what would better be done is e.g. to work from a monochromatic portrait, and spend 2h on a single eye, trying to reproduce it as accurately as possible.
Accurate copy has little practical use for an established artist, yet it's a great training exercice: it helps you develop your vision, sense of aesthetic, material control and hand/eye coordination.
You can still stack geometrical volumes in perspective on the side, or learn to decompose still life objects to geometrical objects, that's a very important skill to develop, but this is overall much easier/faster than developing vision, material control and hand/eye coordination.
