I can get through a task in less than 10 mins that takes some of my coworkers over an hour thanks to a couple of spreadsheets I made over the course of maybe a day or two.

There is no great secret, we just need to complie a lot of information in a specific format from lots of different places. A spreadsheet can just do that in seconds and also removes a lot of human error. Honestly the amount of time I must have saved by not having to remember to use the US date format probably more than makes up for the time it took to make the spreadsheet.
