I feel like the most obvious example of this is the array of things we need to apply self-discipline to, to succeed. Things like: eating healthy, limiting screen time, avoiding (over-indulgence in) intoxicants, keeping up with chores and assignments at work or school, not getting bogged down by the state of the world, being patient with others, and so on… Then people who smoke a pack a day judge others for being obese, or vice versa (pun intended) and it’s a whole mess.
