Believe nothing, question everything and never stop!
When I remember my days as an undergrad, I feel the good old nostalgia of those days when my friends and I gathered in the faculty cafeteria to prepare tests, homework or anything else. However, the challenges are quite different now. Back then the answers were almost absolute. If you were able to read the book and manage to improve your ability to solve logical problems, you were on the other side of the river. During a graduate research, who can say if something is correct or not? Of course, your supervisor (an expert in the field) must have a strong opinion about a subject, but if you find evidence rejecting his/her hypothesis, then who else can give a precise answer? In my own field, there are many questions that nobody has really answered, while some researchers publish papers with vague explanations to incredibly complex phenomena. And inside this whole chaos reside the real beauty of science. Many times we simply have no clue of what is happening. And our sole weapon was created a thousand years ago.

“…after a close room, what hurts them most is a dark room, and it is not only light but direct sun-light that they want… People think that the effect is upon the spirits only. That is by no means the case. The sun is not only a painter but a sculptor.” Florence Nightingale, Notes on Nursing, 1860.
