This is completely up to you! Some people love moving fast and others respond better to moving slow and steady. Upon completing your 3 or 6 months program you may decide to extend it if you are meeting your goals and want to continue this work with more things you want to accomplish. People may change coaches or do several programs but as long as you are getting the results you are after and there is progress in your Life then having someone for longer periods of time can go a long way. Remember, progress = happiness and if having someone supporting you throughout the whole process helps then the option is there.
