I used to love sleeping late on weekends and would've never in a million years thought getting up early on a Saturday is a good idea. Children change so many things in life.
Now I don't mind, in fact, these couple of hours on weekend mornings are my most creative time. At this time of year, it's still dark outside, the city is still asleep and there is no urgency to start the day.
I usually don't have a plan for what I'm going to do. I simply pick a project that I feel most like doing. These few hours are magical.
