As good as I wanted to be, I am as good as I'm going to get

领悟这个让人困惑的句子的含义需要一定程度的英语经验和水平,
先用英语这样解释吧：
As good as I wanted to be = Although I want to be even better
I am as good as I'm going to get = I am already as good as I will ever be
and that's good enough = and that’s good enough for me

放在一起
Although I want to be even better, I am already as good as I will ever be, and that’s good enough for me
也就是说：
尽管我想要做得更好,我已经尽力做而不可能做得再好了,因此,现在的我,对我来说,是够好的.
