Sitting down and making a medium-large project is the easiest path to practicing things you actually want to draw, no matter your skill level.
If you hit a roadblock struggling to draw something just copy a hundred photos of it and get back to the project.
When it comes to non-project practice all you have to do cycle between
>Imagination Drawing
>Primitive Construction
>30s / 1m / 2m Gestures
>Photo Studies
>Master Studies
>Repeat
And that will cover all your bases/fundamentals. No need to complicate it.

A better way to say it is "Aim just above your average". Constantly upping the bar will burn you out but as the other anon said "good enough" will lower your bar. Art practice is no different to any other form of exercise.

Depends which threads you browse and what you're looking for. Arguing theory and practicing peer review with other artists (or even retarded nodraws) can give you direction, and I've seen some seriously inspiring work here. Also shitting on chudposters and participating in art challenges is fun during work breaks. /ic/ may be mostly dogshit, but unfortunately it's still the best art forum on the internet.
