His personal pilot, Mike Flint once asked Warren Buffett which of his career goals Flint should prioritize. The business magnate suggested this method:
Step 1: Write down your top 25 career goals on a single piece of paper.
Step 2: Circle only your top five options.
Step 3: Put the top five on one list and the remaining 20 on a second list.
Easy, right? List A and List B. With this exercise done, Flint confirmed that he'd start working on List A -- his top five goals -- right away. ... Buffett shook his head: 'No. You've got it all wrong, Mike. Everything you didn't circle just became your Avoid-at-All-Costs List. No matter what, these things get no attention from you until you've succeeded with your top five.
The "Avoid at All Costs List" comprises your second-tier priorities. That's focus. They're what you don't do. It's what you ahve the focus and determination to not do. It's saying no (or at least not right now). Eliminate the distractions.
