For those law students who ask about doing a PhD

Q: Should I do a Ph.D.?

A: As long as you're ready to challenge the conventional thinking of anything, of course. People would think you're stupid or crazy for going against the norm, but who cares? A Ph.D. is all about adding new and unique knowledge or perspectives to your area of choice. 

Imagine a circle that contains all of human knowledge:

By the time you finish elementary/primary school, you know a little:

By the time you finish high school, you know a bit more:

With a bachelor's degree, you gain a specialty:

A master's degree deepens that specialty:

Reading research papers takes you to the edge of human knowledge:

Once you're at the boundary, you focus:

You push at the boundary for a few years:

Until one day, the boundary gives way:

And, that dent you've made is called a Ph.D.:

Of course, the world looks different to you now:

So, don't forget the bigger picture:

Keep pushing.
