Firstly, what's the purpose of you (re)learning math? Do you care to make use of the math? Or do you want math to become a hobby of yours? Most math in math books is pretty useless in terms of practicality and enjoyment. I would bet that you've always had an appreciation for math but the math curriculum you went through destroyed any chance of you enjoying it. I'd say you should think of (or find) problems you think would be fun/useful to solve, and then learn the math required to solve them. In the process you'll probably find you don't understand certain concepts, but you can always go back and learn those until everything begins to make sense. Be in control of what you learn.
