No. If you believe that the things you are projecting for yourself are all on the path of your spirit and purpose, then visualzations and affirmations simply strengthen that path.
Visualization is simply a tool -- If the goals you create are from your ego, then that will be strengthened, but if your goals are from your spirit and for a higher purpose, then you can use it to benefit yourself and the greater good.
Zen masters and monks seem to have a pretty linear existence, but people living in progressive societies need tools like time, money, schedules, goals, etc, so while it's good to keep some practices in balance with how the zen masters think, know what is practical for your life and purpose.
