I believe that there are worse things than a person thinking that they're beautiful. Like a person thinking that they're ugly or worthless.
I believe that there are worse things than a person thinking they have a good body. Like a person starving themselves to death.
I believe that everybody needs to feel good about themselves and that there are riskier ways of doing that than taking numerous selfies. Like acting dangerously, sexually.
I believe that if you're having a bad face day or hair day or body day or whatever day, you should be able to find a pose that makes you feel however you need to feel, capture it and do what you need to with it.
I believe it's not fake to keep taking several selfies until you find one you love, with people you love, and that it can result in a photo that will always make you smile.
