I love this quote from David Foster Wallace from his book, Infinite Jest.
Way too often we worry about what we think others are thinking about us. The reality is that they are thinking about their own lives and what they are going through!
The reality is that, frankly, they most people really don't care about you that much as they are very busy with their own set of problems, obligations, and challenges.
Therefore, the good news is that you don't have to worry about what you think they are thinking about you.
Focus on living your life the way that is best for you and sending love and good vibes to others around you.
