Those Days

[Exzachtlee]

Everybody makes mistakes. Everybody has those days.

Or so I hear.
Often, I find myself making ridiculous mistakes throughout certain days. I miscalculate wits, move units in the wrong order, try to attack twice with the same unit, and so on. I just find myself making blatantly flawed moves that I never ever would make on any other day, which in turn, throws several games away. I feel like I'm just flushing easy wins down the drain or condemning myself to ensured losses whenever I have a bad day. Perhaps I didn't get enough sleep. Or perhaps I make one mistake and it puts me on tilt, affecting all of my other decisions.

What happens to you when you have a bad day?
What do you do when you're having a bad day?
How do you avoid making mistakes in general?
