Keeping up with Joneses has been part of our society for some time, but with social networking on the rise with Facebook, Twitter, Instagram, etc., the number of "Joneses" we have to compare ourselves to has expanded profusely.
Humans are called the "comparing creatures." Comparing ourselves to others is how we make sense of life. Comparisons can inspire us to grow and change. Comparisons can also provide helpful examples of what we don't want to be. But comparisons without context don't tell the full story.
Comparing how you look, the model of your cell phone and car, clothes and handbags, and summer travel plans with others develops a rat race mentality. Our lives are then consumed in trivial competitions.
