Letter to a Young Law Student- Don't go to law school: But if you must, take my advice. By Dahlia Lithwick: ... Life is short. Misery is overrated.

I would point out that most of this advice applies to professional school generally. (Especially point A.) And perhaps graduate school generally. (Although liberal arts graduate students are, in my many years of experience, extremely unlikely to forget to have a life. After the first year, that is. Most of them spend the first year thinking, "What the HELL am I doing here?" Even though they usually already know.)

However, liberal arts grad students do NOT get to ignore their grades. At all. Because they kick you out if you fall below a B+/B average. (However, intellectual physics have nothing to do with library school, at least. And I'll bet they have nothing to do with medical school, either.)
