Yes, as a philosophy major, I also agree that anything that is not 20th century philosophy is not really that helpful. It can be interesting academically, to trace the evolution of philosophy, but it won't really scratch that itch of engaging in the big questions.

The biggest value I got out of being a philosophy major was building reading concentration skills - being able to read dense passages takes a lot of commitment and practice, and that can build thinking skills. The internet teaches us to skim and do fast/shallow reading, which doesn't lead to deep thinking. Reading older philosophy is a great way of building those deep reading skills, even if the actual content of those texts is not applicable to modern life.

To the OP, if you see this, I would suggest looking into Experimental Philosophy. It's a branch of philosophy that focuses on using neuroscience to understand how we think about the world. Books like Thinking Fast and Slow may be much more interesting to you.
