Last week was the first time I've missed a newsletter since starting this 10 weeks ago. It completely slipped my mind and I didn't have a reminder set. I made a mistake.
But I'm back, and have learned from it, I now have a weekly Calendar event and a repeating Trello card. Even with both of these things I'm sure I'll miss another newsletter eventually but hopefully not for at least another 10 weeks.
Making mistakes is unfortunate but you can use them to your advantage. Just take a moment, reflect on what went wrong and come up with a plan to fix it.
