If you could delete one repetitive task from your workday forever, what would it be?

Hey everyone, I’m a developer looking to build a tool that actually solves a real frustration rather than just making another "cool" app.

I’m curious. what is that one tedious manual task you have to do every day that makes you think that there has to be a better way to do this? I’m looking for the "boring" stuff: data entry, filing, repetitive emails, etc.

If a software existed that automated that one specific thing for you how much time would it save you a week?
