Struggling at work - looking for tips.

I think all of us auto techs go through this. Second guessing our ability and losing self confidence is a killer. Been there-done that. When I complete a job I always take the extra time to double check my work to make sure its right, even though it takes a little longer. Your wifes suggestion, along with a checklist (in your head) is a solid plan.

X2. Knowing what you're doing is one part of the job. Being consistant is the other. You have to redevelope your habits and take each job one at a time. Just like your wheel torque sequence. (We all torque our wheels, right?). You can do multiple jobs at one time, but just get in the habit of completing each task before stepping away. If for instance, you put a wheel on a car, you put all the lug nuts on and torque 'em. Do that every time and there will be no second guessing. Same with anything. If you put that caliper on, tighten the bolts before you step away. If you have to go check something else out, when you come back you can look at that caliper and say to yourself, "Yeah, that is done".

Sorry if this got long or preachy, I go through this subject a lot. With what I do, a bit of time can pass between one thing being done to the next phase being started. It helps to not have to guess if the previous step was done properly or if it was just "mocked up". It's one of those ounce of prevention things.
