Walter, you have one misconception here. You are not unpolished but a shining star of essay forum I regret that you do not critique as much as you should. You would be made the contributor.
I have critiqued one of essay, the forced divorce one where there were flaws. Here also, I think there are a few.
1)
Such unpolished gem needs to experience the heat of spontaneous combustion
Gems and spontaneous combustion don't go together. Pressure? We polish it and keep polishing to bring out its true beauty or sparkle.
2)
The journey to such nirvana is but easy
is ANYTHING but easy.
3)
challenging destination is about to befall
Incomplete sentence. I am not getting what you are trying to say.
I think there is some more mistakes... but most of all, I think we need some simplicity. There is a nice quality of simplicity that your main idea does get blurred in the verbose words all around.
I still think its a good but 'can be great' essay.
Hope this helps.
