All my friends with PhDs are unhappy, and do not enjoy doing research. They are all intelligent, some a little bit creative, and only curious when forced. They are experts of citations (a tease that never gets old to me, sorry) and I’m afraid are most concerned with not being left behind or achieving prestige.
Having had countless long late-night chats with them in empty bars about this, I gather their habits of conformity got them that far and let them down once they were on their own. They consistently think what I’m doing in my life is more interesting than theirs. I think the opposite and would die to be in their shoes.
These friends are all in mathematics or humanities, and for those in humanities, I would especially die to be in their shoes. I recommend them books on a regular basis, collaborate with them on papers for fun, sending loads of notes that get chiselled down to whatever the editor is expected to prefer.
The whole process is nasty from my perspective. A pile of people desperate to wiesel off the next because that’s the skill they were selected for from early on. In my best effort to put bitterness aside, I can only rationally conclude it’s rotten to the core.
To be clear, these are very intelligent people. But, the system of schooling most go through selects fiercely against curiosity at it’s earlier stages. This is only a theory. Feel free to point to research on the topic.
