Let me show you this.

This is the end screen from a silly online Tetris-type game I play. It’s a daily game where you get one go at it and you either win or lose, and then that’s it for the next 24 hours. I’ve been playing it in idle moments for ages now.
Last year I got a win streak of 80 days before I got distracted and missed a day. Then I kept trying to get my numbers back up, trying to hit that 80 day streak and beat it, and kept failing.
On Friday 9 May this year I got sent back to the start again, and thought it was time I got serious about it. I set a daily reminder on my phone so I wouldn’t forget. Thanks to my reminder, every day since then I’ve remembered to play it, and I got closer and closer to beating that magic 80 day streak.
On Sunday night I was having trouble with a website on my phone so I went into the settings and cleared my browser cache. It deleted my browsing history and my cookies.
On Monday morning I went to play my silly online Tetris game, and when I finished, I got the screen you see above.
Monday 28 July would have been day 80. But I’d deleted my cookies. That meant it was day 1.
I’ll get you, 80 day streak. I’ll see you on Wednesday 15 October. It’s a date.
