Or perhaps sometimes people say P.H.D.
Whenever you want it, just call it.
It will sure come to you in a short time.
But this >> PhD <<, is not something that can be called, summoned whenever you like.
It's a real talk, real biz and a real job.. ... ...
Need a real hardworking brain and a LOT(S) of patience and effort too.
Quoting from someone who had experienced it...
A PhD, by its very nature, is a very individualistic venture. There is no right way to do a PhD (there are however a multitude of wrong ways). This is the first big surprise for people who are starting their PhD having completed their undergraduate degrees -- there are well defined correct ways of getting a degree (usually `turn up to lectures, do course work, revise for exams, use a modicum of common sense') but such prescriptive techniques don't work for research degrees. The award of a research degree effectively says `This person knows how to do research in his/her chosen area' and `research' is a nebulous, difficult to nail down thing which relies on insight, lateral thinking, inspiration and a lot of hard work. An undergraduate degree is a lot of hard work, but doesn't put so much emphasis on inspiration. Most (if not all) people cannot sit down and say `right, today I'm going to have some inspiration'. The unpredictable nature of progress in a PhD means you spend a lot of time not sticking to the deadlines you set yourself. This is dispiriting.
In most departments there's always one smartarse who loudly proclaims that doing a PhD is easy and he (its usually a he) can't see what all the fuss is about, and he's just written another three chapters this morning, and he's submitted another five journal articles. People like this are lying, showing off, from Mars or over-compensating for inadequacies in other areas of their lives (if-you-know-what-I-mean). Ignore them. -Richard Butterworth-
However, I like the first quote on his page...
The only way to find out how to do a PhD is to do one. Therefore, all advise is useless...
