The word “yes” creates opportunity. Research shows that lots of good little things, especially socializing, keep you busy and pave the road to joy.
“No” creates focus. Warren Buffett once said that the difference between successful people and very successful people is that very successful people say “no” to almost everything.
So, how to have both? Balance. Jealously guard your “protected time” for work and play. If you can’t manage protected hours, set aside protected days.
