Human productivity thesis of the day: We should never input corroborated information more than once. If you need to plug the same numbers or text into different places, you are doing too much work (even with copy and paste). The human variable here expands the threshold for error to an unacceptable degree. Systems should be in place to automatically pull that information so that you do not need to. If said systems do not exist, do everyone else a favor and build them. I am streamlining an entire organization through Excel; you can, too. The “data entry” profession should go extinct and give rise to useful tools that save everyone a hell of a lot of time.
