Magnetic strips just sounds like an expensive way for me to drop a ladle on my foot.

The continuity beep got me too when I first started out... it's so easy to just trust that tone and move on. What finally clicked for me was when I had a short on a Cirrus that kept coming and going with temp changes. I was chasing my tail for two days before a senior guy made me walk through the whole circuit with a schematic and a meter set to ohms. He showed me how a simple resistor in parallel with a winding was tricking the beeper into thinking there was a dead short. Now I always kill the power, disconnect both ends, and use the resistance scale to actually see the number... saved me hours on a G1000 pitot heat issue last month. It's humbling but that's how we learn in this trade.

The ukulele guy is a rite of passage in Southeast Asia. I started in a coworking space in Ubud where a "sound bath" workshop happened right next to the silent zone every Tuesday. Switched to a membership at a proper office in Seminyak and my output tripled. It's not just the noise though. The vibe of a place physically changes how your brain works. A quiet room makes you treat work like work. A hostel lobby makes you feel like you're on vacation.
