I think, perhaps, we all vary wildly from day to day. With our fleeting emotions and temporary moods. Some days I forget about tomorrow, and others I dwell on my yesterdays. I do believe that practice helps- meditative practices, self discipline, yes. But it’s so easily undone. A few days leads to a few weeks leads to a different person. One must maintain diligence when it comes to who they choose to be. Or the choice will always be made for them.
