You are all you have got. The difference between doers and dreamers is that the latter wait for the mood before taking action while the former create the mood by acting. Never be bullied into silence. Never allow yourself to be made a victim. Accept no ones definition of your life, but define yourself. Your self-beliefs either support or undermine you.
People are not remembered by how few times they fail but by how often they succeed. Every wrong step is another step forward. First we form habits, then they form us. Conquer your bad habits, or they will eventually conquer you. Quit now, you will never make it. If you disregard this advice, you will be halfway there.
