As a general point of order, I think grad student should avoid comparing themselves to each other as much as possible. Jealousy is a pretty dang fast ticket to craziness, in my opinion.
That being said, this is what Einstein had accomplished by my age (25). Dayyyyy-um:
- Fathered his first son, Hans (he had been married for over year)
- Published hugely influential papers on Brownian motion and the photoelectron effect.
- Wrote and defended his doctoral thesis.
- Conceived concept of special relativity.
