Are the relationships you involved in today helping to build you up, or helping to build you down? There are many things in life that do nothing but take away from who we are; yet we still continue to indulge ourselves in them, because we fear change.
As people it is in our nature to try and stay committed to habits, people, and other patterns in our lives that do nothing to help us grow, and do nothing to help make us happy.
Sometimes what is best for our lives is to simply get away from the things in our lives that do nothing to benefit us, and only act as parasites taking away from who we are and putting nothing back inside of us of nutritional value.
Remember that there are things that do take a lot away from your life, but that help to build up your character as well, so be sure not to give up on things of this nature, use your intelligence, and evaluate wisely.
