There's been studies of people that have complete recall. People that can remember every day of their lives. They've found that the brain areas that are needed to commit long term memories are larger in them than in most people. There's a suspicion that those people have worked their memory so much that the brain has made the needed change. Implying that the more you try to remember things the better your memory will get. But it's all hypothetical right now.

However you can use memory technics that will help you remember. There's the memory palace, there's creating a story so silly about what you are trying to remember that it helps you remember the items and there's also spaced repetition. Which is a technic that reenforces memories just as the brain starts to forget them.

No one really knows if practice improves memory but it can't hurt.
