Our insecurities can really mess with us. We can be skilled, knowledgeable, cute, athletic, talented, but when someone else shows up with something we think we don't have (e.g. a lot of money, a nice body, a bunch of college degrees, etc.), we forget all that we are. We forget all our accomplishments, and only see what we think we aren't or don't have.
We forget that we are all human... unique as individuals, yet connected in the same way to each other. No one person is more than or less than another.
