According to the passage in image_66e147.jpg, what must we do to realize our dreams?

In the middle of the passage, it is explicitly stated: "...और इसलिए हमें परिश्रम करना होगा और कठिन परिश्रम करना होगा ताकि हम अपने सपनों को साकार कर सकें।" (and therefore we will have to work hard and labor hard to realize our dreams). Thus, working hard is the correct answer.
