An ounce of prevention is worth a pound of cure.
Apparently Benjamin Franklin was referring to fire safety when he gave the above quote, but I find it is applicable to many situations, including that of self-improvement.
We have examined previously in this study how our moral resolve is like a muscle, with limited capacity, and a need to exercise and grow before it is strong. But it might be stronger than we realize, if we just started directing it more towards an ounce of prevention than towards a pound of cure.
In addiction recovery they teach that the best way to have a strong moral resolve is simply to not test it. The best way to overcome temptation is to be tempted as little as possible. Consider an alcoholic who goes to the bar with his friends for social reasons, but now must struggle the whole time to not get a drink. He will be quickly depleting his reserve of grit. Once every so often he might be able to pull off some moral heroics and keep himself sober, but most nights he will cave. Consider how much easier it is, then, for him to instead say “I’m just not going to the bar,” and never face its temptations to begin with. He is more sober by not testing his sobriety.
There is still some effort in that, of course. He must look his friends in the eye and say he can’t go when he used to go before, but it is an easier thing to do than see the beer and smell the beer, but not taste the beer.
In my own life I found that once I identified the unnecessary ways in which I was expending my moral fortitude, and circumvented those situations, that suddenly I had far more energy for actually making myself a better person. God works in miracles, it is true, but He expects us to work in prudence and reason.
