One thing that my situation has given me is perspective.
We each have perspective. Based on our unique experiences, we all believe different things. Someone's biggest problem might just be miniscule to someone else.
For instance, if you ask any college student how they are doing, most of the time they will say they are stressed. They will complain about their exams, an upcoming paper or an idiot professor. But the truth is only 6.7% of the world has a college degree. There are people all over the world that would just kill to have those problems, 93.3% of the world to be exact. There are people out their who wake up every day not knowing how they are going to eat. Instead of wondering when and where they will get their next meal, they would love to be in a warm dorm room with unlimited meal passes and no responsibilities except to learn.
I've become so disappointed in humanity at times. I am tired of hearing people complain about things that they should really be thankful for. Or even worse, people who go on and on about problems that aren't real problems. I want to stop them and shake them and wake them up. We all need to wake up. I wish it didn't take cancer to show me that. I challenge you today to wake up. Step back and think about your place in the whole world. Your existence in the grand scheme of time and space. It is so small. The average lifespan of humans is only 71. We have 71 years and our only goal should be to make the most of it.
I am not innocent of dwelling on "stupid" problems. I look back on who I used to be and I am disgusted. I was so vein. Losing my hair if anything changed that. I'm thankful that I have gone through this because it has truly made me a better person. It has made me into someone who is thankful. Someone who will not take their health for granted once they have it back. Someone who will never complain about something that I should be grateful for or something that doesn't matter. Someone who realizes what truly matters in life.
