And the more I drink the more I feel it. That's why I drink too. I try to find sympathy and feeling in drink.... I drink so that I may suffer twice as much!
The rationale for loving others is the recognition of the simple fact that every living being has the same right to and the same desire for happiness, and not suffering, and the consideration that you as one individual are one life unit as compared with the mulititude of others in their ceaseless quest for happiness.
Of all the ways we have found to hurt ourselves, the worse has been through love. We are always suffering because of someone who doesn't love us, or someone who has left us, or someone who won't leave us. If we are alone, it is because no one wants us.
I think the person who has had more experience of hardships can stand more firmly in the face of problems than the person who has never experienced suffering. From this angle then, some suffering can be a good lesson for life.
