It's the action, not the fruit of the action, that's important. You have to do the right thing. It may not be in your power, may not be in your time, that there'll be any fruit. But that doesn't mean you stop doing the right thing. You may never know what results come from your action. But if you do nothing, there will be no result.
It is the best thing to blame ourselves when people cannot get on well with us. Boundless charity necessarily includes all or it ceases to be boundless. We must be strict with ourselves and lenient with our neighbors. For we know not their difficulties and what they overcome.
If we are to stand the final heat of the battle, we must learn to stand our ground in the face of cavalry or baton charges and allow ourselves to be trampled under horses' hooves, or be bruised with baton charges.
