Step-by-step explanation:
The quote, summarized, is basically stating that some people have better stuff than you, but you should be the good kid. This quote in my opinion, means that even when people are seemingly better than you, getting through and flat out ignoring this is probably the better way to go. I can use this in life by applying it to school. If someone has better clothing, better at sports than me, etc, I should still plow through because in the long run it doesn't mean much.
