Last weekend when I was painting my (built in) wardrobe door I noticed something.
It was a sunny day (I know that in itself is weird in the UK at the moment) when I painted that door.
And it was a cloudy day when I painted the actual bedroom door.
But I felt like I'd had a much more productive day when it was sunny.
And I realised that if it is a sunny day, no matter what I do, I always feel like I've been really productive, in comparison to a cloudy day.
I could probably do exactly the same things on a cloudy day and a sunny day and I'd still feel more productive on the sunny day.
