I've tried lots of things but haven't finished any.
joecode: Yes.  There seems to be a common thread here.  You are taking on way more than you, or really anybody, can handle.  I mean, seriously---a program to model the stock market?  That's why everybody else keeps bailing out.  Anyway, if you get a bit more realistic (don't read: less ambitious), then I'm sure you'll be a lot more successful.Failure is actually a good thing, as long as you learn from it.  And it looks like you've got plenty of material in that regard.
