A studious person spends a lot of their time reading and studying, and does it by choice — it is part of who they are, not just what they must do this week.

The feeling of the word is mostly warm but slightly distant. It praises the person's seriousness, yet it also paints them as quiet, indoors, a little apart from noisy life.

Because of that shading, calling someone studious can be gentle teasing among friends, though it is never an insult.
