爱的代价, what is it??????

Anybody still remember the song 爱的代价 by 李宗盛? Lately, I like to listen to old songs because it made me think of old times, some good memories I had with friends and family back home. People I have miss.

What is the real meaning of 爱的代价? There is the phrase no such thing as free lunch in this world so everything has its price to pay. What is then consider as a good price to pay for the things and lessons we learn in life? A question I have been asking myself every now and then however I always come up blank. So lost sometimes. When everyone else is working so hard to survive in this cruel world, I still have time to sit around and waste my time. Emotional me is taking over the logical me lately. Lack of sleep I asked myself?
