Focus on the 20%
I am a huge fan of the 80/20 rule. I believe that by ruthlessly focusing on the 20%, you can see sweeping improvements with minimal invasiveness. Note, I didn't say minimal effort.
You see, changing the 20% often requires a LOT of effort -- but it's effort applied with precision.
Change the 20% of meals that you eat 80% of the time... and you don't have to fuss or think so much about your occasional meal out.
Change the 20% of your work that really matters, you'll reap disproportionate rewards (hint - responding to emails and attending meetings are NOT that 20%).
Change your go-to stress reliever, the one you use most of the time, you can completely transform your health.
Identify your lowest hanging fruit 20% and the 20% with the biggest potential to impact your life in a positive way.
Those 2 changes alone will transform your life.
