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?
You, methinks you think you love me well;
For me, I love you somewhat; rest: and Love
Should have some rest and pleasure in himself,
Not ever be too curious for a boon,
Too prurient for a proof against the grain
Of him ye say ye love: but Fame with men,
Being but ampler means to serve mankind,
Should have small rest or pleasure in herself,
But work as vassal to the larger love,
That dwarfs the petty love of one to one.
This is what enlightenment is all about - a deep understanding that there is no problem. Then, with no problem to solve, what will you do? Immediately you start living. You will eat, you will sleep, you will love, you will work, you will have a chit-chat, you will sing, you will dance - what else is there to do?
You see, if you take pains and learn in order to get a reward, the work will seem hard; but when you work... if you love your work, you will find your reward in that.
