The meaning of life...

Looking up to the sky, dreaming of the bright future ahead of me... the most crucial element of all has surprisingly lied beside me, regardless of what and how I will do in any aspects: 信(Xin, fourth tone), which can be translated as integrity, faith, sincerity, trust. Doesn't this Chinese character summarise the factors of success in life, study and work, as well as the virtue of being a real good person?!
