I’m picturing sending patience to the gym, patience doing some strengthening exercises that involve renewing the previous night’s speech, patience doing some crunches, patience doing jumping jacks.
And, in a way, patience really does need practice, it does need strengthening. If one cannot be patient in small instances then big ones will be ever out of reach. Do a little bit of patience practice and the capacity for patience grows. But don’t overdo it. I know people who confuse tolerance for patience and let it consume their will. That will not add up to good. That will tax the will until it breaks. There is a big difference between patience and putting up with something.
