Its been a while since i played it but, In the main town (the first one you go to) there is a homeless guy sleeping in one of the ally's. If you have stealth as a skill, Do what i did. When he goes asleep, enter sneak mode and face the corner beside him. I held the analog stick down with a bit of tape so i kept sneaking in the corner while the guy was asleep. Then just flick over and watch some tv, or do whatever you gotta do, and when you get back your sneak level will be up a good bit. I know its cheating but it helps a whole lot when your sneak level is high.

Just check back now and again to make sure your still in the corner and that the guy is still asleep.
