Answer:
Let's be real. We all want to help people because we don't want to be seen as snobby or pretentious. However, why are there so many homeless people on the streets begging for food or clothing? Why are there people in 3rd world countries who don't have their basic needs met? Why is the list of people who need organ donors so long? It's because we all want to believe we're good people, but in reality we rarely go out of our way to help another human that's just trying to survive.
So yes, I would like to say I would help if a lot of people are sick. But is this a valid answer if there are billions of people on Earth who could use my help? It's not. I truly believe that until I actually take action in a selfless, altruistic manner, I can't really answer your question truthfully.
Together, we can make a difference. Let's smart small. Today, try to brainstorm ways we can make the world better. Why? Because it's our duty to help each other and make the future a little brighter for those who will come after us. Don't do it for the incentives. Don't do it for the acclaim. Do it for "no absolute reason."
