the way to go
Wasting 4 months to stupidity is certainly the way to go.
Think back to the last time you acted really stupid.
The largest stupid spree that I took was over a girl, during which year and a half I was blissfully unaware of my own stupidity. Would I do it again? Difficult to say. Most of the time we are stupid it is willfully so (Parris' most famous quotes come to mind).
Laziness however, is, in large doses, inexcuseable. I have never been so miserable as when I think about time and money I've previously wasted being lazy.
