On Rosh HaShana there's an introduction to the Artscroll Siddur that impresses upon us that we're supposed to be better than we are, and all of us are supposed to be chastising ourselves (to a degree) for not being better than we are, on a regular basis.
Chazal, early behaviorists, suggested that we be in a constant state of improving, look back between meals and regret how we’ve messed up the past couple of hours. We’re supposed to do tshuvah , repent and change, between breakfast and lunch, before we eat dinner, and then again at bedtime. By the time we get to Yom Kippor we’ve done tshuvah for the year, need only think about the day.
Great Jews do this.
