But sure, if all that you care about is success and you happen to define success like most other Americans (i.e. by making the most money) then go ahead and work as hard as you can and make that million. But please don't complain about your burnout when you're 30-40.
There is way more than money and work in this live. Don't work too hard especially when you're young. If you waste a year or two, nothing will run away and your opportunities will still be there when you're 25.
