Discipline vs. Regret

I heard a quote the other day that I think is worth sharing:

"The pain of Regret is worse than the pain of Discipline."

In how many areas of life could we avoid the pain of Regret if only we submitted to the pain of Discipline? It reminds me of another quote I heard many years ago from an elderly friend:

"Do what you need to today so that you can live with yourself tomorrow."

Wise words.
