Action changes things. Change of perception changes things. Doing something changes things. Whatever your vision is take steps toward that end. However, if what you are aiming for does not include other people then I would say you are aiming for the wrong thing.
Life is about relationships.
There is no easy way sometimes and unfortunately we must endure and even though it seems the darkest, there is always another point of completeness and happiness somewhere up ahead even though we may have a hard time believing it. However, it is having a vision of how things CAN BE that makes the difference in how things WILL BE in your future. Accept the pain and transform it into something that will change not only you but the lives of others as well.
