it takes a lot of luck to be successful

there are a lot of talented people in this world,but only few of them might be successful.why?that's becacuse luck is a very important factor required to be successful.we can't always depend on luck.we also need to make ourselves prepared to accept any challenges in our lives.and then if luck visits us.we might succeed without too much effort.if we can't find any opportunity to use our abilities.we can say to ourselves,i have done my best,i am just unlucky.so our point doesn't mean we are supposed to surrender to our fate.but we should also realize the importance of luck.we can't deny the truth that someone around us who are less talented than us succeed easily due to luck.so we should work harder to fulfil our dreams and wait the moment that luck approaches us.

这句话是说成功需要的运气成分比较多的意思，你月是正反那么可以从chance这个方面说起。譬如，No matter how much efforts you make, if there is no chance to show them,nobody would know these efforts.
