#5 in Robert Louis Stevenson's 12th Commandment of Life is.....
"Don't let your neighbours set your standards. Be Yourself."
Don't compare yourself with others. Don't compare your lives, your achievements, your career, your family life, your successes in different areas. Just be happy with yourself and what you have.
Here are some other "Be Yourself" Quotes I like:
"Always be Yourself because the people that matter don't mind and the ones that mind, don't matter."
"Be Yourself. An original is always worth more than a copy."
"Be Yourself. That is something that you can do better than any other. Listen to the inward voice and bravely obey that."
"Be Yourself. God gave you shoes that fit you. So put 'em on and wear 'em."
"To be Yourself in a world that is constantly trying to make you something else is a great accomplishment."- Ralph Waldo Emerson
