Just a thought.
What if the first hour is the most critical to the success of the rest of our day? It's that way for the development of infants (success being the rest of their lives, not that day), so why wouldn't that be true for us on a smaller scale? In The Creative Habit (no, I haven't read it yet), Twyla Tharp talks about having a personal victory first thing in the morning.
Since having this mindset for the last three days, I've had three victorious mornings. Nothing over the top, but I make sure not to do the things I'll feel bad about later (checking Instagram, email, getting on the computer, not making my bed, etc.) Keep the important things at the top of the list. Get them done. Move on. Boom. Happy day.
