If you approach each day with the intention of doing, saying or producing something meaningful, and if you don’t measure every word you speak or action you take, you’ll eventually be rejected.
This leaves you with 2 choices: You can choose to interpret your intelligence, your brand or your character based on those who reject you, or you can choose to focus on those who care enough to support you and believe that you matter.
It seems to me that devoting attention to those who don’t believe you’re up to snuff would be utterly exhausting.
