maybe there IS some gaavah mixed in with self interest and the Simcha of doing the Boreh’s will.
i can hear the Yetzer HaRah speaking to you, the frum Yetzer HaRah, the trickiest disguise he uses.
when you get to the level of the Chofetz Chaim, then it’s time to start seriously worrying about that gaavah in the mixture. now just try your best to do it as much l’shaym Shamayim as you can.
just do it. you know your Tatti will be happy even if it is not yet Pure.
