Love is without a doubt the laziest theory for the meaning of life, but when it actually comes a time to do it we find just enough energy to over-complicate life again. Any devil can love, whom he himself sees as, a good person who has treated him well, but to love also the polar opposite is what separates love from fickle emotions.
For this will cure him that is sick, and rouse him that is in dumps; one that has loved, it will remember of it; one that has not, it will instruct. For there was never any yet that wholly could escape love, and never shall there be any, never so long as beauty shall be, never so long as eyes can see. But help me that God to write the passions of others; and while I write, keep me in my own right wits.
Depression is a serious problem, but drugs are not the answer. In the long run, psychotherapy is both cheaper and more effective, even for very serious levels of depression. Physical exercise and self-help books based on CBT can also be useful, either alone or in combination with therapy. Reducing social and economic inequality would also reduce the incidence of depression.
