For your engine to function effectively, mechanics have prescribed that you service it regularly. I remember father asking us to "warm" the car every morning even though he wasn't going anywhere. I always wondered why he did that but with time I came to
realise that failure to do that may result to failure of the engine. A five minutes exercise would save you hours in a mechanic workshop. It's the same principle with writing. If you don't "warm" your pen daily or regularly, it becomes blunt and takes more time to start writing.
