As is shown in the picture, a librarian is telling a boy that the book named ”How to Do Well in School Without Studying” is in the fiction section, which suggests that there is no shortcut to learning.
From my prospective, I do agree with what the picture implies that there is no shortcut to learning. Learning is just like building a house and you are supposed to be whole-hearted when you build it first. More hard-working you are, more stronger the foundation will be. However if you work casually at the beginning, the house is actually in danger and at the risk of collapsing.

Plenty of aged-old sayings about studying are not far to seek ,from which we can learn that there is no free lunch in studying as well. Though the technology develops rapidly in today’s world,”knowledge capsules” is non-existent but a ridiculous fantasy in science fiction just like the given picture.
There is no better instance than language learning ,which requires lots of time and energy spent on alphabet ,word memorizing, pronunciations and master(ing) grammatical rules. Hard efforts should be made if you want to succeed (in) it.
In conclusion, it is significant for us to learn by heart rather than searching for a shortcut .As the saying goes, nothing in the world is difficult for one who sets his mind on it.

From my prospective perspective (Two different words with different meanings, look them up if you are interested), I do agree with what the picture implies that there is no shortcut to learning. Learning is just like building a house and you are supposed to be whole-hearted when you build it first. The more hard-working you are, more the stronger the foundation will be. However if you work casually at the beginning, the house is actually in danger and at the risk of collapsing.

Plenty of aged-old sayings about studying are not far to seek ,from which we can learn that there is no free lunch in studying as well. Though the technology develops rapidly in today’s world, ”knowledge capsules” is are non-existent but a ridiculous fantasy in science fiction just like (Are you referring to the picture you mentioned in the beginning? If so, use the "in" before the definite article) the given picture.
There is no better instance than language learning, which requires lots of time and energy spent on alphabet (should either be plural "alphabets" or "a particular alphabet") , word memorizing, pronunciations and mastering of (The "of" is not necessary) grammatical rules. Hard efforts should be made if you want to succeed it (You can either once again write "language learning" or otherwise use "in it". Just writing "it" which is supposed to refer to the act of language learning does not suffice in particular case).
In conclusion, it is significant for us to learn by heart rather than searching for a shortcut. As the saying goes, nothing in the world is difficult for one who sets his mind on it.
