Get rid of the negative people that are around you. Negativity does nothing but consume you and you will in turn become negative. When you surround yourself with negativity you cannot get anything positive out of your situation. When you place yourself around a group of positive people, you can grow.
If you have dreams an aspirations you will need to place yourself in an environment that will allow you to conquer those dreams. Positive environments and people are a big part of that!
