Practicing Language alone

Has anyone got any ideas on how to practice a language with no language partner, I know reading is one example, also I have heard people say they talk to themselves, I was thinking along the lines of the latter idea, but it usually get tired of imagining out conversations? Anyone got better ideas??? Oh and I do practice with a language partner twice a week also, so just letting ye know.

You could just narrate your own life, tell what are doing, describe what you are seeing, how you feel.
