Just need to know.....

I have read alot of great information here on visa's and their types. And as I am not done (i have alot of resources to read through) I had simply one question, and please if it's easier to point me to a link then great. Exactly how easy is it for someone who doesn't have any real reason for moving to the UK other wanting to get out of dodge, move there? So far the things I've read have been covering information on visa processes though I am not exactly sure any of them cover my intentions. Thanks in advance.
