人生不是要超越別人，而是要超越自己ge英文係咩?

未有時間查，不過大約係咁：

The goal(objective) of life is to surpass yourself(oneself).

我相信你指的美國作家Og Mandino II 的名言：

To surpass the deeds of others is unimportant; to surpass your own deeds is all.

There's no need to override others, but yourself !

there is no need ....

Life is not to get across others. It is to get across yourself.
(It is only my translation.)
