I’m not trying to get all existential on you here.
Don’t think of this question in a freshman philosophy class, staring-at-the-sky-and-pondering-mortality kind of way. Rather, apply it to the smaller things you do every day.
What’s the point of standing in this line?
What’s the point of getting up so early?
What’s the point of showering?
It all comes down to motivation. A storyteller must always ask this question of the characters who populate the story. The answer to this question should never be “there isn’t any.” That’s crazy. Every action leads to a reaction. That’s science.
You’re reading this right now. What’s your motivation? To be entertained?
If so I apologize.
(Note: If you google “What’s the point?” you will find a plethora of insanely depressing discussion forums. I mean, there are some real options out there for bumming yourself out. This question really lends itself to gloominess.)
(Note#2: I then did an image search for ‘happy depression’ and got some awesomely weird results that cheered me right up. Pizza popped up, for some reason, and a woman who appears to be going insane. I have included both for your edification. You’re welcome.)
