I wish. Nowever it's not uncommon to build frustration that way. Let's disregard the fact it's a highway to unhappiness. One day, one may not have enough energy to keep this frustration at bay, then anger will flow. Anger is a funny thing, it can lend you temporarilly a lot of energy (that you pay back with interest later). So even if you didn't have any for compassion, suddenly, you might find you have a lot for destruction. Now don't get me wrong, I think trying and failing at compassion is a worthy action, even when resulting with destruction. In fact, some meditation technics are mostly that: you try to be compassionate, or in the moment, or just observing. You fail. You try again. For years.
