No matter how tired you think you are when your alarm clock goes off, force yourself out of bed if you want to have a productive morning.

By the evening, your brain doesn’t expect any blue light exposure and is very sensitive to it. And most of our favorite evening devices emit short-wavelength blue light.

Ultra-productive people avoid meetings as much as humanly possible. 

Donuts, soda, and other forms of refined sugar lead to an energy boost that lasts a mere 20 minutes, while oatmeal, brown rice, and other foods containing complex carbohydrates release their energy slowly, which enables you to sustain your focus.

Don't allow e-mail to be a constant interruption:

Nothing sabotages your productivity quite like bad habits.

People who are regularly bombarded with several streams of electronic information cannot pay attention, recall information, or switch from one job to another as well as those who complete one task at a time. 

We freeze up when it’s time to get started because we know that our ideas aren’t perfect and what we produce might not be any good.

It takes you 15 consecutive minutes of focus before you can fully engage in a task. Once you do, you fall into flow, a state of increased productivity.
