A little planning goes a long way:

STEP 1 (5 Minutes) Set Plan for Day. Before turning on your computer, sit down with a blank piece of paper and decide what will make this day highly successful. What can you realistically accomplish that will further your goals and allow you to leave at the end of the day feeling like you've been productive and successful? Write those things down.

I have found it is best to do this first thing in the morning.

I like to stand up every hour to break up all the sitting I do.

STEP 2 (1 minute every hour) Refocus. Set your watch, phone, or computer to ring every hour. When it rings, take a deep breath, look at your list and ask yourself if you spent your last hour productively. Then look at your calendar and deliberately recommit to how you are going to use the next hour. Manage your day hour by hour. Don't let the hours manage you.

This is helpful for pulling out of sidetracks.

Continually improve your routine with feedback.

STEP 3 (5 minutes) Review. Shut off your computer and review your day. What worked? Where did you focus? Where did you get distracted? What did you learn that will help you be more productive tomorrow?

Get better every day.

Rituals are an important part of life automation:

The power of rituals is their predictability. You do the same thing in the same way over and over again. And so the outcome of a ritual is predictable too. If you choose your focus deliberately and wisely and consistently remind yourself of that focus, you will stay focused. It's simple.

Life automation frees our mind to focus on important decisions.

Summary: Get Up, Be Amazing, Sleep.
