"Some people think, that the book - is the best source for knowledge of all aspects of life" 
I disagree with people, who think so. Books - is just one of many tools for the knowledge of being, which has no absolute advantages over other means, such as your own work, communication with intelligent people, lucid dreaming, traveling and so on. I'll just try to guess it what things some people find books dignity; then I'll tell you, what to my mind is the "best source for cognition of all aspects of life"
Books are customary to us, since recent time books have become a traditional way of leisure activities for the masses of people. Almost all the people pay their taxes, and hence they can use public libraries, so bookish education is affordable.
Furthermore, there are variety of written thoughts directions: we can find reflections about eternity in it, and at the same time there are encountered detective stories and cheap novels.That is to say, on the grounds of moral and intellectual development, one can find any answer to his question. 
But the problem consists, that not everyone have the adequate development of creative thinking. That is, not everyone can grasp the whole text of the book in its notional scope; moreover, frequently it's assimilated not what was written in the book, but what was presented by the reader, who, perhaps, can by not quite sober-minded.Thereby it was generated entire sections of ugly information,that  infest the information field and which can't entail nothing good.
In my view, the best method of cognizing life - communication with intelligent, skilled, wise people, let us call them "Elders". Elders can explain everything distinctly, and, noticing that if the information wasn't internalized right, they will rush to explain it again.Their knowledge are always based on practice and never are the result of sick imagination.
Well as a good method of knowledge as cognition yourself in persistent labor. Life starts with one person, thus, it’s reasonable to begin life’s knowledge with the cognition of one person. Labor is a check on durability and viciousness, finding strengths and weaknesses. In sum, with communication with the elders, these two methods are more than replace reading any books.
Of course, books are good, but only as an addition to real activity. Life itself  can be learned only in the process of yourself exploration.

pros

Low ticket price. You must agree that traveling by train is much cheaper than by plane or even by bus. And students in general can travel for half the cost.

Large and convenient route network. Not all cities have airports, but there are stations and platforms even in villages. There are many junction stations where you can easily transfer to the desired direction.

You save time and effort if traveling by night express train. It is very convenient to take the train in the evening, and in the morning upon arrival immediately go to see the sights of the city, because you already slept in the train.

Trains are less likely to arrive late than airplanes.

More space in the car. You can lie down, walk around the car, sit, maybe even do yoga :)

Most stations are located in the city center. Thus, you save time and money when transferring from the airport.

Not so hard bandwidth control. At the entrance to the car, you just need to show your passport to the conductor, and you can take your place, you do not have to go through the inspection procedure like at the airport.

You can bring food and drinks in unlimited quantities.

Large weight of baggage allowed for free transportation. You can always take up to 50 kg of hand luggage with you in a wagon.

Of course, train romance :) Tea in the company cup holder, landscapes floating outside the window and the pacified noise of the wheels make the trip more soulful.

Minuses

Long travel time. Some cities have to get about a day.

The condition of the cars. Unfortunately, we do not always observe cleanliness and order in the car. And the conductor is in no hurry to eliminate obvious breakdowns that interfere with a comfortable trip.

Not enough personal space. If you are riding on the bottom shelf, get ready for the neighbors on top to sit on your shelf. And if you are riding on the top shelf, you will only have to lie down when the neighbor below will lay his mattress.

In the reserved seat, be prepared for constant noise and all kinds of smells, and in the summer - also for the heat.
