The favorite corner usually earns its place through use, not intention.

Nobody designs a favourite spot. It emerges: the light happened to be good at that hour, the chair happened to be there, you sat in it once when you were tired and then again, and after a few months the room has a centre it was not given. Attachment follows use rather than the other way round.

Rather than planning a perfect reading nook, watch where you already end up and improve that place slightly. A better lamp, a small table, a cushion. Following your own habits is cheaper and more reliable than trying to design them from the beginning.
