In one sense, social skills are incredibly complex, it has been argued that the actual reason we grew such large brains was to make complex societies possible, not to solve practical problems. On the other hand, social skills come naturally to most people, like learning to walk or talk, so normally it takes no effort at all. But because it's natural and innate, if you're not wired for it, you can imagine how hard it would be to learn to walk - I mean it took until very recently until we managed to build walking machines. As to advice, the only way to learn is exposure. Spend a lot of time with people and try to mimic their behaviour.
