Evidence

I wasted three hours every week doing the same things. Copy data from one spreadsheet into another. Send the same "thank you" email after every form submission. Post every new blog article to Slack.

Within a weekend, I had automated all of it. The spreadsheet sync, the emails, the Slack posts — running on their own, without me touching a thing.
