how to remember something well?

I can remember things well

Repetition. یا make it interesting.

سے طرف کی putting it EVERYWHERE.
Like nicknaming your Pokemon.

As the others have said... that and, آپ could possibly make flash cards, sing about it, یا write it down on paper over and over until it's engraved into your brain.

I'm not really one to talk to about remembering things, though. I forget things easily unless it's something important. It's so sad! xD
