Rawa, are you sure that was written by a native speaker of English? It's very strange phrasing. (on second thought, it could be African English) Friction means the rubbing together of two things to create heat or resistance. So, it could mean 'how do you reduce the reluctance/resistance you feel about getting into the habit of doing something regularly". That's how I would interpret it, but I also find it difficult to understand. You aren't alone! :-)
