Never lie to yourself. And never lie about yourself.
When I was younger, I would lie all the time about the way that I felt. I would tell people that I was perfectly fine when I wasn't. I would tell people that I did something that I really didn't do just to look more likable.
Now, I just feel that if you lie about yourself then you lose who you are ....
.... and who you are is the most precious thing you have.
