You can't start the next chapter of your life if you keep rereading the last one.
I need to remember this. A mistake does not define me as a person, it is a learning experience. I've learned a ton of stuff in the last few years. I've academically learned enough to be awarded an MA in American Studies. I've learned how to clean historical documents. I've run my first (and 2nd, 3rd, 4th, and soon to be 5th) half marathons. I've realized I'm not a good hot weather runner and should avoid it at all costs.
Of course, I have lots of lessons still to learn. I have to learn to give myself a break in terms of my weight. I have to remember that I'm good at my job. I have to remember that even a bad workout is better than no workout. I have to remember (this will sound pathetic) that people like me and that I have friends who care about me. If I can close the chapter on my doubts, I am sure the next chapter will bring untold joy and happiness?
What chapter in your life would you like to be able to close? What do you want the next chapter in your life to be about?
