This is something that observers of other people say. They pass judgement on others mistakes and question ‘why don’t they learn?’. Yet often it is a judgement of themselves.
Learning isn’t that simple. Firstly, we assume that others are aware and more importantly we are judging others behaviour as wrong or a mistake, but only through our filter of right and wrong, good or bad. What do they need to learn for us to be content?
The other thing about learning is it takes time, we have to break habits, we have to feel enough pain to change, we have to learn vulnerability, we have to learn to detach ourselves from defending our way of doing things. These changes do not happen overnight and it requires patience, sacrifice, and being brave.
Learning and change go hand in hand, they are personal and it comes from within, not from pressure from others.
