Lesson learnt, how to do it better, what actions you will do when it happen again (which you already did, check the discipline to execute the plan when it happen). put it somewhere you can see to remind you when you see pattern repeating again in future, you will be aware, capable and handle it well.

You can do it man ! keep it going.
