Goals Essay and "Vision Statement"

Alright, just read through a chapter of "88 tips for MBA Admission", and they said you need to have both a short-long term career goal AND a "vision statement" about how you plan to change (or what you see needs to be improved) in the chosen career field you're looking to do.

For example, if you say you want to do some fund management in China, you talk about the specific type of work you want to do (that one we call know), and then tie it to a very specific trend in China, like "even though they are growing very fast, there is a lack of fund managers to ensure a healthy growth, thus I want to focus on X and Y skills in Fund management and leverage the skills I get from an MBA to ensure a healthy and fast economic growth in China blah blah blah" (I'm making this up, so bear with me )

Does anyone else have their "vision statements" done or will be including one in their essays?

My long term goal is entrepreneurship in Asia... I really don't know what to say other than the standard and cliche "there are many opportunities in China to find a niche market and grow it, blah blah", maybe talk to a few entrepreneurs and see what they find to be good startup markets in China and do some research on that. Do you think that will be good enough, or is the vision statement too specific for most schools (because of the word limits)?

Thanks!
