Considering the large amount of younger folks on this board, I really disagree with advising people to work 17 hour days 7 days a week. I'm not going to dwell on the obvious dangers of your health when getting less than 7 hrs of sleep and no exercise and of course social and other dangers (such as getting an ugly wife
). You're only young once and you're not going to be able to buy it back. Even if you make the big bucks down the line and you're sitting in you Ferrari, do you really want to look back on your youth and have nothing to show for it? It's hard to have good memories when you never left your house.
I'm not saying not to work hard, I'm saying that (especially if you're in your teens or twenties) you need to get out experience life not just work.
