I had a fall again a few days ago and I was fed up. I just couldn't figure out what I was doing right when I had my recent streak of 42 days, and why I have not been able to come close to that since. Yesterday, it hit me a little bit. It's no great chiddush, it just finally clicked a little. The key isn't just to keep busy and avoid the bad things, because eventually you will not be busy at some point. The point is to be busy with Kedusha and Torah. Yesterday, I started taking notes while listening to the daf-yomi shiur on my computer (usually I just listen without taking notes, which inevitably leads to spacing out). And then later at night, I went to a fantastic chassidus shiur on the parsha. I felt like I was living, and I realized as I was driving home that I had no interest in the shmutz. It doesn't compare to Kedusha. So while I knew that I had to live clean and grow, I had forgotten what it really meant. Yesterday I finally felt it again for the first time in a while, and hopefully I can continue to chase it.
