100,000 hours to being exceptional- gooder than good

Been reading Malcom Gladwell's book Outliers. It takes 100,000 hours of practice to be exceptional at something. So today I asked someone at work how much time do they intend to spend getting good. Her response was 8 hours a week on weekends. So we sat down and calculated that she might become exceptional in 230 years. 

How are you spending your 100,000 hours?
