How can I practice for memory palace?

I created memory palace today. I can memorize 10 things and remember it easily but I don't know how can I improve and be faster in memory palace. Let's say I memorized 10 words. Will I use the same route to memorize the next 10 words? If I use the same route, will I forget the words I memorized before? Also, do I need to choose a different place for the new memory palace in order to add new words?
