Just want you guy's opinions really, What does the average hacker want?

I have done some reading about it, And it appears to me that most evil h4x0rs just want to use your computer as a platform to attack other computers or to perform illegal activities on the web via your IP addresses.

I have had a bit of a security scare recently, but it does not appear that many hackers are after actually getting to your documents? Or am I wrong in assuming that?

Some people have said its about learning which seems to be common, and some even leave little warnings about what they did.

It all begs the question, Why ME!

I would just like your opinions on this really.

(Sorry if this is in the wrong category)
