Monday was a bad day
- I woke up late
- I was late for a meeting that I'd organized
- I forgot to submit my timesheet
- I got a hateful email from a potential friend
Maybe it wasn't such a bad day.
- I got to sleep in and had wonderful dreams.
- I don't like meetings. Being forgetful is bliss.
- A friend forgot his timesheet too 
- I only lost a potential friend
I guess anything can be positive
