I want to share the thing that finally helped me with perspective drawing after years of struggling: I stopped treating perspective as a set of rules and started treating it as a description of how space actually works.

Every perspective 'rule' is derived from a simple fact: parallel lines in 3D space appear to converge to a single point when viewed from a fixed eye position. Once I understood why the rules exist, applying them became intuitive instead of mechanical.

I practiced by drawing boxes in two-point perspective until I could do it without thinking. Not interesting boxes — just plain rectangles in space. Hours of boxes. Then I drew complex environments by thinking of everything as box-like volumes first. A building is a box. A car is a modified box. A human figure can be blocked in as boxes.

The Drawabox course is genuinely good for this, and it's free. The homework is tedious on purpose — the tedium builds the visual intuition you need.
