Today’s academia is much like being in the circus, except in this circus you are the ring master, fire eater, juggler, clown, acrobat, tight-rope walker and every other single act inside the tent. There is no support act. You are the main, and only event.
Here is a crude representation of the evolution of the academic job. In a galaxy far, far away, it looked like this:
I know this is a little simplistic but it was a reasonably simple job.
Alas, it has now morphed into this:
There are no more hours in the week than before. This is upsetting, I know. This is what academia looks like now. Yet, you are perplexed why it is so hard to find time for writing. Wonder no more. This is why.
And of these burgeoning responsibilities, what exactly have you been trained for? By now, most people have been trained to teach classes (though not-online). You have been trained in some aspects of research via your PhD. Everything else you have taught yourself. Every single thing.
You are already an entrepreneurial academic, albeit, not through any choice of yours.
