Lately, I've found myself thinking a lot about the following questions: What is good research? And, going further, what makes a good researcher? Below, I've compiled some readings I found valuable. They didn't hand me any definitive answers (I will share my thoughts once I find them), but they were rich food for thought.
[Readings]
How to focus on important problems instead of chasing trends
You and Your Research (Richard Hamming)
How to find a good work-life balance
The Awesomest 7-Year Postdoc or: How I Learned to Stop Worrying and Love the Tenure-Track Faculty Life (Radhika Nagpal)
