Memory trouble

Hello,

Does anyone else have memory problems?

If I can explain this right, it’s like with my hobbies (model railway mainly at the moment), I learn how to do one thing like wiring for example, then I move onto another part of the hobby and learn that part. But it’s as if learning the new thing pushes the memory of the last thing I learned out of my head! 

I have a basic understanding of the last thing that I learned but I am put off switching back to that thing again because it’s like I have to re-learn it all again.

I hope that makes sense.

It drives me mad!

thanks

Ade
