What matters most to you may not matter most to someone else, but ultimately I would like to believe that we all have the same goal.
Living in peace and harmony with one another. We are all here for a reason. We all have different gifts from God to share with each other. When we realize that our life is short and the people in it are blessings from God; we may begin to appreciate them and others just a little bit more.
Not everyone you encounter is going to be nice but it's up to you how you react. You can be a jerk right back or you can make up your mind to be an example of what love and unity is. Love , peace and unity come from God.
