Anney - yes sunlight is a huge factor. You see me when the sun comes out and then goes behind a cloud every 15 minutes. I rush around and get something started, only to fall in a heap when the clouds come.

I was also one often accused of being lazy when I was younger, I was never good enough or did a good enough job.

Interruptions are one of my killers to motivation, but I have posted about that before.
