Find the Fault.

Our greatest enemy is ourselves,
But of course, you have probably already heard this.
Someone, not too long ago, made mention of this fact.
But we never did believe it.
Because how could I ever be the obstacle that stops me from being the best?
Sometimes I believe I can get things done.
Sometimes I believe I am the best.
Sometimes I believe I am good enough.
But then again, I guess that is the problem,
I only believe in myself sometimes.
