Someone said that, a person's life has three days: today, yesterday and tomorrow. Yes, life is not very long, whether we live it fully and meaningfully or not, it all depends on our thought.
In the complicated life, no matter things go smoothly or not, one should have a source of power and happiness, a fulcrum to support one's entire life and soul. This fulcrum can give you the courage and motivation for life, let you see the beauty of life through the plainness or even pain. To find this fulcrum is enough to make you taste the meaning of life in confusion or from hardships.
There are many ways of life, the only way that doesn't exist is the way back. We should take the last failure as the next experience, only in this way can we walk out of life.
