What is your favorite way to learn a new language, product, or tool?

For me, I prefer hands-on, with nearly all self discovery and as little guidance (written or instructor-led) as possible.

This helps me understand if something will be intuitive for me (and therefore I can budget a smaller amount of time or non-focused time) or if I need to dedicate a significant amount of focused time and energy, or even find instructor-led or curated options for learning.

How do you learn? Or maybe the better question, how do you prefer to learn?
