Many years ago I found a Reader’s Digest quote, photo copied it, and stuck it up on the wall. I don’t recall the exact quote nor how/why I had a copy of Reader’s Digest, but paraphrased the quote went something like this.
Pick the three things you care about most. Maybe it’s family, church, and a career. Maybe it’s a career, a hobby, and your pets. Focus on those three things and say NO to everything else.
Easier said than done.
