If you’re the one holding up the line, the stick in the spokes jamming the process, either through inadequate experience or study or attention, be annoyed. Pay more attention. Be better next time.
Once you’re better, though, don’t be satisfied. Clocking along to a step-by-step exercise is not the fish we need you frying. Do your part well enough; don’t be the reason the steps get tripped up. But then get back to work on the steps and the processes of your own design.
For some work, the cost of messing up is just greater than the benefit of doing it really well.
