It seems almost without fail that generosity of spirit requires that we will have experienced if not suffering, then at least frustrations, things that seem to want to stop us from moving in the particular direction that we have chosen.
It is probably something like your muscle. If you want a good muscle tone, you work against it, offering it resistance, and it will grow.
Deep down, we grow in kindness when our kindness is tested.
– Archbishop Desmond Tutu
