It’s important to keep in mind that there is not a “perfect” route to the development of a healthy and positive body image. What works for some will not work for others, so it’s important to identify what you know you’ll enjoy doing. Additionally, if it turns out one method doesn’t help much, you can create a new resolution at any time. Constantly working on smaller goals will make the “big” resolutions possible.
