That is great.
I want to tell you about my experiences when I did that though. A year and a half ago when I tried to get sober for the umpteenth time, I heard a woman say that she needed rides, so I gave her my number and started to pick her up. She started calling me everyday and I couldn't say "NO". It turned into more of aburden to me, and I ended up not being able to stay sober.
Keep your boundaries up!!
