To Daimoku or not .

I try to do Gongyo and Daimoku twice a day. I feel that an early Gongyo ,say around 6-7 am , really gets me going . I chant for 20 minutes and then do Gongyo. In the late afternoon I repeat the process. Even if I don't feel like doing it I force myself and never regret it. My problem is negative thoughts (fundamental darkness ) and chanting really helps.
