Love yourself and love others.
Be kind to yourself and others.
Be forgiving of yourself and others.
Be patient with yourself and others.
Don't think you are better than others or that they are better than you.
If you do these things, you will be happier. You will be more at peace with yourself and others. If you practice these things you will understand better the love of God. God is loving even when we aren't. He is kind and forgiving. He is patient with us. When Jesus walked on earth He did not act better than others. He washed His disciples feet. He ate with sinners.
Have a great day!
