I cannot give you the formula for success, but I can give you the formula for failure--which is: Try to please everybody.
Herbert Bayard Swope
I've been guilty of this in the past. I use to worry about what others thought, if others were happy. My own happiness came second to everyone else's. That's when I learned that I really had to be number one in my life. Everyone is going to feel the sting of disappointment. So trying to please everyone is only hurting yourself. Sometimes, it's ok to be a little selfish.
