My short advise on how to study math: Learning mathematics is similar to learning how to ride a bicycle. You can watch many people ride bicycles, people can tell you how to ride a bicycle but you don't really learn it until you attempt it for yourself at least a few times. Clearly, you shouldn't expect to succeed in your first try and until you show me someone successfully riding a bicycle on their very first try, don't tell me that you have no talent for math.
