A morning routine involving no phone, computer, etc. for the first hour of the day has been great for me.

I usually wake up, make coffee, read for about 30 min, and then gratitude journal and plan my day. (I use Panda Planner purely for convenience, I'm sure a blank sheet of paper works as well.)

This allows me to set my own schedule and prioritize my day, rather than reacting to the demands placed on me by others. I've seen improvement in both 1) my general productivity and 2) my progress on the long-term tasks I'd usually be more likely to put off.
