"This can be more difficult than one would think as we spend years, decades even, not knowing what we want and practicing different habits and thoughts that contradict each other."

That really is the issue. Change can be hard on its own but if one doesn't know what he or she wants to change, he or she just ends up spinning his or her wheels and not getting anywhere.

I like the framing devise of "tuning" and "vibration" here. It functions very well and adds a nice hint of poetry to the discussion.
