But discipline absolutely requires a high level of maturity. The maturity to live by principles not preferences. The maturity to delay gratification not effort. The maturity to prioritize purpose over comfort. The maturity to choose higher standards over lower standards. The maturity to reinforce those high standards when no one is watching and when everyone is watching.
Once you see the relationship between discipline and maturity, you’ll recognize how people struggle with discipline not because they’re incapable but because they’re not mature enough yet to choose it and do it. You may recognize this in yourself.
