Believing my sentence

My sentence has to do with self confidence. Some days, I actually feel okay about my sentence and don’t have any conflicting thoughts, which makes me wonder if I picked something too “easy,” or not quite new enough. Should I pick something different for the rest of the month? Should I try to push my sentence further on the days that I feel okay about it until I actually do have some conflicting thoughts? Should I just be okay with believing it those days? Thanks!
