If you don't retain your memories after reincarnation then it's not you, it's separate entity.
I'd focus on improving your current life and helping others instead of thinking too hard about what comes after. We will find out anyway so why worry?

It's a separate form, yes, but it inherits the same Will driven by You. A life in this world is only for You to experience new perspectives, to understand Your position and existance better. That's why not having memories of Your previous lives can be beneficial.

However, you can remember past lives, and there are methods of making it more likely. These methods have mostly died out in the west thanks to Christianity, but they involved rituals meant to channel or tune in to your ancestors. The belief was that you reincarnate as one of your ancestors, or rather they streamlined their lives and traditions so that you would be more likely to reincarnate through your decendants, therefore remembering more easily.
