You can create multiple links with the original names at once with commands like:

  ln -s path1/files* path2/

or

  ln -s path1/* .

Doing that helped me remember the order because I knew my command could end with a directory as the destination and links would be created there.

Sometimes hardlinks are useful too. You don't always need -s

Edit: Why was this downvoted? I didn't see anyone else mention it until after my post and to me this was an easier way to remember the order than comparing it to "cp".
