How Can I Improve My Memory?

I'm 14 and I felt like I have been loosing my memory this past month. I forget where I put things and things like that. I don't want to loose my memory when I'm this young. What are ways that I can improve memory.

Suggestion:

If you put a weird object in a weird place (Like a banana on top of your window sill) it will trigger your memory and help you remember where you placed something if you lost it.
