As a teenager, I hated my body with a passion. I couldn't see that anyone else could be worse off than me and was totally obsessed with wishing it perfect. My body confidence didn't change whether I was fat or thin, because I would only ever see the 'bad' parts. I was miserable, ashamed to be me, and going out would take ages because nothing would ever look good enough.
However, with practice and patience, anyone can learn to not only accept what they have, but embrace it.
It's ok to have goals BUT, it's also VERY ok to love where you're at right now.
