Thank you for slowing me down!
Have I said "thank you" to you yet? Well, I'd better hurry up, so here it goes:
THANK YOU! for getting me to finally stop running like a horse into battle (language of the mesilas yesharim); and for slowing me down, like the Ramchal says, to think about what I was doing. While active in the addiction, one can't think, one doesn't think.
It's only because of the 90 day challenge that we finally have a chance to realize things that we never realized before!
