Many tasks in the workplace could be done with total adequacy and barely more.
Don’t get fixated on ensuring that every task is entirely done, every email edited and re-edited to get the grammar right, or every spreadsheet is flawless. This is a pointless pursuit.
Sure, you don’t want to be a careless hammerhead. But don’t waste time sweating the little stuff. There comes the point where any changes you make to whatever it is you’re working on no longer makes it better but just different. Identifying the inflection point of diminishing returns is one of the hardest skills to learn and one of the most necessary.
Don’t agonize over tiny improvements in your work and thwart yourself from achieving the actual goal of doing the work.
