Go back and read all those books you were supposed to have read in high school.
It turns out, they are actually really good. And now you're old enough and have had enough life experience to understand and relate to them.
I remember kinda liking "The Sun Also Rises" in highschool literature class. There were these people travelling around Spain and drinking a lot. I could relate. At some point in my late 20s, I came across a copy and read it again. Turns out it's an awesome book, and about more than just swilling wine.
So the thought occurred that since one of those terrible highschool literature books was good, maybe more of them would be. I grabbed The Great Gatsby. Awesome book. Whatever JD Sallinger thing they had us read. Awesome. Joseph Conrad, Jack London, Oscar Wilde. Hell yeah. And all those authors had tons of other great stuff they'd written. And there were lots of authors in the last hundred-odd years. It kinda kicked off a lifetime of seeking out the Good Stuff.
One minor downside, as long as we're doing a PSA, is that doing this will kill your ability to read Airport Bestsellers of any genre. You'll need actual good writing from here on out. Fortunately, there's lots of people still doing that so they should be able to crank out new good books faster than you can read them.
