Answer: Since this is a broad question, I will use the book Wonder.
When I read Wonder, it was about a boy who had a "messed up" face, and was builled by it. Throughout the book, he makes friends and do well in his classes, however is still being builled. He even meets a love interest. This inspired me because it shows that no matter how different you are, you can still find people who care about you, and you can still shine. Just because you're different doesn't make you a freak, be yourself.
Yes and no, a scale can help by telling if you are losing or gaining weight but the downside is that it can also discourage you. It can make you feel like you are not making any progress at all or it can make you feel like you have gained weight.
