We struggle to get things done. It is because our time is finite. It is not endless. We all know it, but some of us seem to forget about it every once in a while.
It is not possible to remain always productive. When I say productive, I am referring to be doing something you think is worth your time. Something that not necessarily gives you money, but that is the thing you would do if you look back to the past in the near future.
"You can do anything, but not everything." — David Allen
What are you going to do today? Is it worth your time?
