The problem with long periods of no practice is that you think you are doing great, but then realize that your technique has atrophied.
We all want to be instant experts. One of my sensei describes this in terms of the training montages that are standard fare in martial arts movies; the neophyte progresses from clumsy beginner to skilled pro in thirty seconds of cinematic snapshots. The rest of us suffer from dissatisfaction and disappointment from being less than optimal for much longer.
