My experiences pretty much mirror those expressed here. You would think that hoarding/saving/safeguarding financial security is an innate skill in humanity, but alas if you come with no money then any financial windfall calls for a celebration (by you, or by a leech in the family) and poof there goes the money.
It's quite tragic. Whoredom doesn't seem to be a step on the ladder of success alas. It IS quite tragic.
