If you want employ consistency to be who you want to be, then just check the box!  It is, in fact, important to check the box.  It is a record that you are doing the deliberate things you want to do to be the person you want to be.  If we could choose a word to remove from the english language it would be the word "just".  "I'm just reading one paragraph" or "I'm just writing one sentence'" or "I'm just reviewing one vocabulary word."  If you are focusing on what you are doing in that moment you are focusing on the wrong thing.  The focus is on how many days in a row you are doing just that thing.  Writing just one sentence for 1,211 days consecutively is much more than just writing a sentence, it is doing what you need to do to become who you want to become. It is winning - consistently! Keep Streaking!
