As has been mentioned, it is important to cut out anything that isn't getting your the most results and that will disturb your focus.
Also, if you can put what ever possible on autopilot so that you can jump right in without having to think or plan first.
You can do this by creating a checklist. I like to do mine in excel.
Put everything on it that you must do and are your top 80/20 activities, this would include time to manage your outsourcing tasks. Put a time limit beside it and use a timer to remind you when your time is up.
Use project blocks of time and put them on the list under project (#1, #2 etc) and use that time to focus only on the project you need to be working on.
You don't have to do everything on the list every day, you can even code it if that helps (I use something like this for my housework and use an e beside things I do every other day, or you can put M,W,F for Mon, Wed, Fri for example)
Get a bin or deep basket for each project and label it. Put everything in it that you need and put anything in it that you will need the next time you work on it. Pull any files etc that you need the next day the night before.
This helps procrastination a lot. I find when I have things out and ready in the morning, I am not as tempted to browse and veg until I fully wake up :0)
This concept is what I call doing my BOOST circuit, I have found it useful for almost any area of my life.
