"one career I would like is very very hard to get and it will take years of hard work without money".

That one sentence from your post would be a good start to find your ideal work. If what you want to do takes too long, look for things within that realm that really appeal to you.

Most work falls into categories i.e. health care, accounting/investments, technology/design, administrator, teaching/child care, social services, restaurant/food, blue collar work such as construction or truck driver, etc. Not all-inclusive list but you get the idea.

I recently read that some people in the US who would like be a physician are opting for physician assistant school because the cost and time investment are so much less ... a creative solution, I think.
