Just remember: every person has doubts about their body and/or their appearance from time to time. I don't care if they are a cover model, a leading actor/actress, or just the average person you cross paths with; we all have moments of doubt concerning our attractiveness.
To me, true beauty comes from believing in ourselves and having confidence in our own skin. So, don't feel like you are the only one out there with doubts and most importantly, don't get discouraged from working on your self-improvement goals.
For, we all have parts about our body that we aren't necessarily proud of, that we would rather NOT be seen, OR that we may even be disappointed in.
But the most attractive people are the ones who don't act like it bothers them.
