The monkey mind is not a big problem. The monkey mind is just thoughts that are hopping about.
The big problem are the beliefs, ideas and assumptions that motivates your meditation and your actions.
For example, you may believe that you are a nobody and that you have to work hard in order to become somebody. You may believe that poor people are stupid and lazy.
Or you may believe that you have to be positive, relaxed and wonderful.
You may believe that life is utterly meaningless.
You may believe that you are an idiot or a jerk or that you are...
You have to examine your beliefs, ideas and assumptions if you want to improve your meditation. The monkey mind is uninteresting.
