Someone once told me that the reason that we come to Earth is to learn lessons. They said that before we come to Earth, our soul agrees to undergo certain experiences in order to learn specific lessons. Sometimes, if our soul does not learn the lesson, we are forced to repeat the action until we learn. So sometimes the reason that you keep slipping up on your diet, or a certain person keeps walking back into your life, is because you just have not learned your lesson yet, and this same thing will keep occurring until you do. I feel like even though this is just a theory, that it applies perfectly to my life. I can only hope that I can learn my lesson soon so I can move on to the next part of my life.
