Let me not to the marriage of true minds
Admit impediments. Love is not love
Which alters when it alteration finds,
Or bends with the remover to remove:
O no! it is an ever-fixed mark
That looks on tempests and is never shaken;
It is the star to every wandering bark,
Whose worth's unknown, although his height be taken.
Love's not Time's fool, though rosy lips and cheeks
Within his bending sickle's compass come:
Love alters not with his brief hours and weeks,
But bears it out even to the edge of doom.
If this be error and upon me proved,
I never writ, nor no man ever loved.
It seems that for some people the idea of compassion entails a complete disregard for or even a sacrifice of their own interests. This is not the case. In fact, you first of all have to have a wish to be happy yourself - if you don't love yourself like that, how can you love others?
If you find a neighbor in need, you're responsible for serving that neighbor in need, you're responsible for loving a neighbor just like you'd like to love yourself.
