原句是：I have discovered,as perhaps Kelsey will after her much-

I have discovered,[as perhaps Kelsey will after her much-publicized resignation from the editorship of She after a build up of stress],that {(abandoning the doctrine of "juggling your life",and making the alternative move into "downshifting" )brings with it far greater rewards than financial success and social status.}
专业术语已经忘记了,要是还在高中我一定能说出来,不过句子的关系还是说一下的
[]是插入语之类,{}是discovered的宾语从句,（）是宾语从句的主语
整个意思就是：我发觉XX带来了XX,就像kelsey在XXX后将会明白的
will后面省略了discover
句子意思清楚了就都很好分析了吧

are you sure that nothing was left out in this sentence in your typing?? i mean the sentence
"as perhaps Kelsey will after her much-publicized resignation from the editorship of She after a build up of stress"
