If you just want to feel the happiness of life, you should really pursue short time relationship such as a physical one.  If you want more, you may try long time relationship.  A long time relationship can offer you happiness, pain, hope, disappointment, boringness, frustration, and many more. Most people, especially woman, are only prepared for some of them such as happiness and ownership. This more or less makes their lives more miserable. The fact is nobody is happy all the day. If that were the case, it would be very boring also because you don’t even know what pain is.
