If you want to make changes in your life then yes, you should listen to subliminals every day. Especially in the beginning.
The false beliefs or bad programs running in your subconscious mind currently did not get there overnight.
Listening to a subliminal daily will change your beliefs and install new programs allowing you to manifest what you desire into your life.
Subliminals change your beliefs through repetition. For best results, you should listen daily without skipping days for at least 30 days. From there you can move on or use the subliminal for maintenance if needed.
