A is for acceptance. Accepting what you cannot change and learning to live with it. Accepting yourself for the amazing person you are. Live your life for you not for the expectations of others.
Accept your accomplishements and learn to gracefully accept the compliments given to you. Really you have earned them.
We tend to be our own worst emenies as we can find all the things wrong with ourselves and we don't look at the positives. Start looking at the good qualities you have and embrace them. Forget the things you don't like as you focus on the ones you do, the ones you don't will disappear or fade.
If you are a writer, accept your writing. Share it with others for critique, remember the feedback you get is not directed at you, but directed at making your writing better.
Should you get an acceptance letter for anything be like this young lady and share it.
Remember acceptance is a good thing.
