Sometimes you get frustrated. Some part is really hard to access, or the instructions weren’t clear, or it just isn’t going right. Maybe you can see yourself getting careless, tossing tools around, skipping steps. Maybe you’re trying to hold too much in your head at once and forgetting details. Sometimes you get that feeling that the ground is rocky, so you just have to plow deeper. Force your way through. That’s the feeling you get right before you break something. So stop. Just stop and stare for a few minutes. Maintenance is a game of mental strategy, rarely a game of force. If it feels off, if you’re confused, if you feel like you just want to get through it, just stop.
