Always testing my understanding of new programming languages, libraries or concepts by playing around with them until I could mentally "walk around" them like I

Always testing my understanding of new programming languages, libraries or concepts by playing around with them until I could mentally "walk around" them like I can mentally walk around my neighborhood[1], then being drawn to the next thing just outside my field of experience and understanding. In short not moving on before mastery, then moving on after mastery. [1] I think this analogy is fitting because the drive that makes write five versions of a three line function feels similar to the drive that makes me choose whatever path I haven't walked down before when going to some errand or another.
