It’s easy to say “fuck it, what does it matter?” After all you’re just a speck, one out of 7.5 billion people on this planet, not to mention the billions that have came before you and will come after you. So yes, you wouldn’t be wrong to say “fuck it”. This is the nihilistic approach. It’s not wrong either. You can definitely make a case for “fuck it.” But this approach is too easy and in a strange way more comforting than the opposite. After all, by saying “fuck it” you can remove all responsibility. Why does one have to do anything at all if it’s not going to matter in the end?
The opposite approach is to say that all life has meaning. It doesn’t matter if you’re the president of the United States or a high school janitor. To be alive is to have meaning. This approach is harder than simply throwing up one’s hands and saying “fuck it,” it’s less comforting too. When one believes that there is meaning to life it all of sudden puts the weight of the World on their shoulders. You take on responsibility. It means becoming aware of how you affect others, how you affect the World.
