You don't mention why you work 82 hours a week, but balance is the key, and if you really work 12 hours a day 7 days a week and have plenty of money, there's something else to the equation. Most jobs that allow for "plenty of money" are either / or propositions - you sprint until you can't take it anymore, presumably with the possibility that you won't have to take it anymore a lot earlier in life than 65. You're running down the track and the train is coming behind you - you can jump off any time you want, but the train will pass you by.
Anyway, you probably know the answer already - you'll never find the time if you work 82 hours a week. As suggested, get a really good office system and listen while you work, if that's possible. Listen in the car, as you do. Save your money for expensive home gear until you can really use it. -Kirk
