These thoughts ocurred to me this morning... I wonder if I've got the 'equations' right! ;)
If you're not innocent, it is difficult to have faith (you know the truth, you know what works and what doesn't, you know how bad the world really is, you understand where others are coming from and don't trust people). If you don't have faith in anything, it's difficult to succeed. So, success will have to start (and continue) with innocence. It should be possible to retain one's innocence even with increasing success!
If you believe that you're not ignorant and know just about everything there is to know, then you don't want to learn or rather you don't think there is anything to be learned. If you don't learn, you're not gaining any wisdom. So, you need to start with ignorance to gain wisdom. It should be possible to be ignorant and wise at the same time.
