If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
My aim is to understand love. I know how alive I felt when I was in love, and I know that everything I have now, however interesting it might seem, doesn't really excite me.
But love is a terrible thing: I've seen my girlfriends suffer and I don't want the same thing to happen to me. [...] Although my aim is to understand love, and although I suffer to think of people to whom I gave my heart, I see that those who touched my heart failed to arouse my body, and that those who aroused my body failed to touch my heart.
In proportion to the love existing among men, so will be the community of property and power. Among true and real friends, all is common; and, were ignorance and envy and superstition banished from the world, all mankind would be friends. The only perfect and genuine republic is that which comprehends every living being. Those distinctions which have been artificially set up, of nations, societies, families, and religions, are only general names, expressing the abhorrence and contempt with which men blindly consider their fellowmen.
What are wanted ...are not Constitutions and Revolutions, nor all sorts of Conferences and Congresses, nor the many ingenious devices for submarine navigation and aerial navigation, nor powerful explosives, nor all sorts of conveniences to add to the enjoyment of the rich, ruling classes... but one thing only is needful: the knowledge of the simple and clear truth ...that for our life one law is valid - the law of love, which brings the highest happiness to every individual as well as to all mankind.
