From the moment we begin our lives, we're learning. It's imperative to surviving, to growing - don't walk in the shadows, it's dangerous, don't touch the fire, you'll be hurt. These days, most continue to hone this natural instinct with formal schooling, but that's certainly not the end all, be all of knowledge. If you go to school or not, if you have the opportunity or otherwise, you won't stop sharpening your mind after those formative years. That's just not the way our incredible brains work.
You, specifically, have actually decided to something equally incredible: you want to really dedicate yourself to learning a skill, and what better way than an apprenticeship? Formal or informal, you're under someone's tutelage, absorbing everything they can teach, growing closer to them in the process...
...unfortunately, though, you've gained a little something extra with that bite from the fruit of knowledge. You've fallen for your mentor.
Do you realize this pitfall immediately, or will you have to learn the hard way?
