Bin off your crap jobs!
I think we've probably all got a job (or 10) that we just hate doing, for whatever reason!
Usually we keep them because the customers are really nice (but the job is an absolute nightmare) or it's in the middle of a row that we do...etc, etc, etc.
Put the price up to match the job or bin it off.
It may not speed up your day, or make you quicker, but mental health plays a big part in our game and if you're happy, you work better and more efficiently.
