Answer:
The correct answer is: Growing up is complicated and challenging, but is ultimately worth it for what can be accomplished.
Step-by-step explanation:
In his poem "If", Rudyard Kipling is advising the younger generations about some situations and possibilities through their life, by encouraging them spiritually and morally to go through their growing up period patiently and proudly, because at the end they will grow up and be decent and honest people: "Yours is the Earth and everything that’s in it, / And—which is more—you’ll be a Man, my son!"
The author appreciates honesty and patience, where he acts as a father figure, and advises his younger audience to pursue their dreams, but without losing their grasp on reality.
