Focusing on your core activities prevents you from spreading yourself so thin that you become mediocre at everything, and excellent at nothing. When your mind is scattered, you can never be really consistent in your efforts. And your results will show this lack of clarity. To remain productive, you must block out chunks of time in your day and work exclusively on your top priorities. During these peak performance sessions, turn off your phone, email, and any other potential distractions.  Put your head down and get some work done. 

Indecision is detrimental to your success. Make a decision and stick to it. Direct your efforts in one direction, towards achieving a specific goal. Completion boosts confidence – it clearly highlights the progress you are making. You can point at something with ride and say, “this is what I have accomplished.” Multitasking is just a fascinating distraction. It often delays the completion of a project.
