Many fine points here.

Of course a strong will might lead us towards the best outcomes or the worst ones. It depends whether it's in service of the true Self or of the Ego.

And I agree most people don't really know themselves. That's a big obstacle in relationships (you cannot improve what you don't know).

I'm glad that you fond a way to enhance your life. I believe our personal growth should be life's main goal ("The unexamined life..." etc.) - whatever the tools we use.

Pharmaceuticals can offer a chemical "crutch" when we're weak, but of course cannot ever heal the soul. :-)
