How long do I need to practice?

How long does it usually take to prepare for a class when we focus on the task at hand? A student with a history of unpreparedness showed up today all prepared. I asked her, "how long did it take to prepare to this level?"

“Not very long” We both started laughing. Procrastination often takes up more time than the time needed for the task.

If I can help you learn to practice effectively, call me.
