I compeltely agree this remark.It often hits me that life is so long that i will feel nothing if i don't make fully use of time to do more significant things. Why i think so? On one hand,some significant things outlast life's length.It is ofen the case that if i spend many times to help the homeless,i will feel happy and it's significance outlasting life's value. On the other hand,what i do will changge somebody or something ,which is honorable for me . So what should i do ? Primarily,tireat my parents with pacience ,such as traveling with them ,making meals for them,caring for them and so on. Maybe the time that my parents accompany me is less and less.What's more,do utmost to help those in need around me.For exampie,i can help my roommates solve problems care for their psychology healths.Last but not least,read more books,travel more countries and try to improve myself.I think i don't get struggled in a boring job and i should do more signicant things not to disappoint myself beacuse i only live once. In a nutshell,it is doing sidnificant things that can make lie more significanct and valuable . It's up to different expectations.Only i do,what i expect outlast life' length.
