Life changes. We change. Don't get so caught up with fact that your life has changed, focus on the change and embrace it. We are not meant to be the same person we were when we were younger. That's why God created wisdom! Wisdom comes with change and embracing it.
And if you're not happy with how you are currently, give it some time . . . it WILL change!
Make one good choice today, it can lead to another! God Bless- Kara Lea
