While I agree with the need to push yourself, and it might have worked for you, I disagree that this is a lame excuse in general.
Good work requires focus. Whether you can work and handle school at the same time also depends on your course load. If you are spending 70 hours a week on classes, an extra 40 hours a week (though not impossible) might not be worth a decrease in performance in both activities.
