How long does it take to become a good trader?


Something someone said in another thread got me thinking...How long does it take to be a good trader??? Not just profitable but consistant new account highs?
IMHO I would say 10,000 hours, thats almost 6 years of screen time. I put in +7hours a day on the us index's and 3-4 on the euro every night which I think really helped. And it took about 10,000 before my account stopped with the large swings and replaced with the more easy on the stomach new highs, higher lows.
