20:52 Yesterday I already mentioned the book Overlap.
Today I had a long and great talk with my spouse about the same. I am doing too many things at once. Or better said, I am trying to focus on two many disciplines at a time.
In the book Sean McCabe describes it with fires that you are trying to keep burning. Try to keep five fires burning at the same time; none of them will grow into a bonfire. All will hardly burn and nobody won't ever notice them. But if you invest all the effort and all your energy into one fire, this will be seen far away.
So, we talked about, what I could and should focus on and it also needed some kicks in the ass to not focus on two projects at a time.
Let's light one fire at a time.
