Do not chase people.Be you and do your own thing and work hard. The right people who belong in your life will come to you and stay. Do not think since something bad happened in a relationship that the world is over. Sometimes we think that we will never have someone who loves us like this person. Yet, if this person wants to leave your life just let them walk out. Do not chase them ! If someone really loves you they will show it. You may have problems but still they would not leave you enough for you to chase them so dont. If things are meant to be they will fall in place.
Sometimes when you least expect things to feel right they do. Humans can only take so much from a person and when you have all things going right for your life you should surround yourself with happy positive people who bring you up in life. Work hard focus your time on something, such as school or money (or BOTH). 🙂 You will see your life change before your eyes once you change your mentality.
