Had a conversation with Matt. He came up with some very good sentences which I cannot remember mere minutes later, but essentially:

First sentence of this section should be something like "In the discussion you will come up with some problems that you can fix or things you can improve."

Then this paragraph should read something like:

"Make actions that will improve things by the end of the next iteration. Some problems may take longer to fix, in which case you should try to make an action that will start the process of improving it by your next retrospective." 

That's pretty clunky, sorry. Matt, what you said on the phone was better - I hope this reminds you...
