A lot of people like to just show up when they travel. I'm like that, too. But even six months after I'd gotten here I was still groping around in this society like I'd just gotten off the bus. I'm still learning more everyday, too. I've met some very good, honest, hardworking people, very devout and moral. That is the typical Nepali-really good people. But somehow Thamel and many other parts of the Kathmandu Valley are home to some of the most greedy scoundrels you will ever run across-not anywhere near the majority of Nepali, but the other ones are so busy working and living that you are not likely to meet them unless you are here for a while.
So, now I have a great book, well not a literary masterpiece by any stretch, but it will save you a lot of money and help you to be safe and problem free while you are here. Well, no one is problem free in Nepal, so there is a lot of information on how to deal with problems.
