The word discipline doesn’t usually make you think of something enjoyable. Having discipline isn’t usually fun. Instead, it can actually be painful, especially when it requires some kind of sacrifice.
However, painful discipline is necessary to achieve certain objectives. And the more difficult the objective, the greater the discipline required.
This quote (author unknown) reminds us that no matter how painful discipline is, it’s nothing compared to the feeling of regret from not having it. Yes, discipline is not fun. But a little bit of it can go a long way.
