Re: PhD
^ Nicely put. Just one addition (if you agree):
Well, if anyone decides to go for a PhD, the most important factor should be the supervisor. Forget, city, university ranking, brand name, etc. If you find a good supervisor, that would make your work more effective and the impact factor would be higher. If you just wanna do a PhD to label yourself a Dr., then ofcourse your decision depends on how 'easy' it is for you.
