Study hard so that you can master technology, which allows us to

Hear the fiery counsel of Che Guevara, whose words rise like a call to arms for the youth of every generation: “Study hard so that you can master technology, which allows us to master nature.” These words are not mere encouragement for scholars in their chambers, but a trumpet blast to all who would shape the destiny of humankind. For in this short utterance, Guevara binds together discipline, knowledge, and power—the sacred trinity by which humanity wrests its future from the grasp of fate.

To study hard is not simply to gather facts, but to strengthen the mind as the warrior strengthens his arm. For knowledge is the spear with which mankind pierces the veil of ignorance, and discipline is the armor that protects the spirit against despair. Without study, there is no mastery; without mastery, there is no freedom. Guevara’s command echoes like an ancient law: only through study can we command the tools of our age, and only through those tools can we command the forces of nature.

Consider the great tale of the Industrial Revolution. For centuries, humanity bowed to the limits of muscle, wind, and water. Then came the engineers, the inventors, the dreamers who had studied the laws of physics and chemistry with relentless effort. With steam, with steel, with electricity, they harnessed the power of nature—heat, motion, light—and bent it to human will. Rivers that once roared wild turned the wheels of mills. Fire that once threatened cities became the energy of progress. None of this came by chance; it came because men and women studied, mastered, and dared.

Yet Che Guevara’s words are not merely about invention—they are also about liberation. For to master technology is to seize independence from those who would control it. History shows us that nations who neglected study became servants of those who advanced. The conquest of lands, the domination of peoples, the shaping of empires—all these often arose not from stronger armies, but from superior mastery of tools. Thus, Guevara’s warning is clear: if the people do not study, they will forever remain under the yoke of those who do.

But mastery must not become arrogance. To master nature is not to abuse her, but to guide her with wisdom. For the earth is both mother and teacher, and if we ravage her with thoughtless tools, we destroy ourselves. The true meaning of Guevara’s call is not domination, but stewardship: to use technology with vision, discipline, and compassion, so that humanity may thrive in harmony rather than in conquest.

So what lesson, O listener, should you carry into your life? It is this: devote yourself to study with relentless discipline, not as a burden, but as a path to freedom. Learn the sciences that unlock the workings of the world, learn the tools that define your age, and learn also the wisdom to use them rightly. Do not be content with ignorance, for ignorance chains both the body and the soul. Instead, let knowledge be your sword and your shield.

The actions you must take are plain: dedicate time each day to learning, whether through books, through practice, or through observation of the world around you. Embrace curiosity as your constant companion. Do not shy from the hard disciplines—mathematics, engineering, sciences—for they are the keys that unlock doors of mastery. And above all, remember that knowledge without purpose is hollow; let your learning serve not only yourself but the greater good of your community and the world.

Thus, Che Guevara’s words must be remembered not only as the command of a revolutionary, but as an eternal truth: “Study hard so that you can master technology, which allows us to master nature.” In this command lies both a warning and a promise. The warning: those who neglect learning will be ruled by others. The promise: those who embrace it may rise to shape destiny itself.
