You are intentionally misunderstanding but I will explain for others.

To correct your analogy: We have a destination in mind. We know it's down this dark and rainy road. I can't foresee every twist and turn on this road and I am able to be at peace with that.

This makes me a better driver because I am able to focus my heart and soul and energy on the road on front of me, without being distracted by what I don't and can't know.

I control the controllable and I know the knowable - and I do that no less well than when I was areligious. The difference is now I give no thought to the uncontrollable and unknowable - that's on G-ds hands. I focus on what's in mine.
