I heard that you should read 50 ayahs a day. I read surah Yassen every morning, it is 83 ayahs but they're short and I don't feel like I actually read 50 ayahs. My question is should I read more or is the 50 I'm reading fine. I have no problem reading more but when I do I'm less consistent. What can I do?

The 50 you are reading in Sura Yaseen is fine and highly recommended. However, I recommend that you occasionally read 50 verses from other chapters as well so your mind is blessed with all the beautiful chapters of the Qur’an.
