"Be yourself"?

Someone who I consider the ultimate people pleaser posted this on her FB page. How I wish the world worked this way!!

No matter how loud their opinions are, others cannot choose who you are. The question should not be, 'Why don’t they like me when I’m being me?' It should be, 'Why am I wasting my time worrying what they think of me?' If you are not hurting anyone with your actions, keep moving forward with your life. Be happy. Be yourself. If others don’t like it, then let them be. Life isn’t about pleasing everybody.
