When I look back at my most productive days, it's the one where the first minute of my working day was diving right into the most important task of the day. Then staying focused on that for the next 1-2 hours.
I think the easiest way to actually do this is to avoid these three apps until after working two hours:
It can wait!
Yup, surfing the web can definitely wait.
Don't let others interrupt you in your first two power hours of the day.
I'm sure you may have others that you could cut out. Maybe even try turning off your phone for that two hours.
I love starting at 8:00 am and by 9:45 am having that feeling of already getting a ton accomplished for the day. It makes the rest of the day so much better.
