On carrying on

Sometimes its the wanting that is most exhausting. Or it is when you're busy telling yourself that its impossible, out of reach, been done by others before you, out of your league and other stupid things. Attempting to better yourself is hard enough when you're nearly alone in an impatient, demanding city. But nigh on impossible when its you holding you back. What then? Give up? If only I could! But that's the one thing I don't know how to do.
