Show respect even to people who dont deserve it, not as a reflection of their character, but as a reflection of yours -from Lifehacker, quoting Dave Willis. I really need to remember this because I think I show weakness when I do this, but I shouldn't.
The power of gratitude is huge and can transform your life. Being grateful for what you already have can attract more of it in your life. It doesn't matter if your glass is half empty or half full. Just be thankful you have a glass!
