Sketchbook artists

I’ve recently become entranced by the idea of improving my drawing skills and consequently picked up books on the subject of sketching. I like how artists, when interviewed about sketching, have such varied habits around keeping a sketchbook:

Some have drawn since childhood and other started in adulthood.
Some sketch daily, others can go through phases.
Some plan their sketchbook pages, others don’t.
Some draw from real life, others draw from their imagination.
Some use their sketchbook for experimenting, others use it as a journal.

I don’t know what kind of sketchbook person I will be, but the only way to find out is by dedicating time to it!
