To me, thoughts are like layers of a building. Maybe best to imagine you're exploring a labyrinth with deeper and deeper layers.
- Things you idly think to yourself from glancing at something are layer 1 thoughts. "The cat is blue." "That person is attractive."
- Layer 2: "the cat is blue, someone must have painted it" and "That person is attractive (to me) because of how they dress and their high cheekbones"
- Layer 3
- layer 4
- layer 5 "...and why does that person dress that way? Did they feel pressured to dress so well because their beauty was always praised?" Or "will that cat be okay? I know that blue paint often contains polymadeupethyline, which can ruin the appetites of humans - will it have the same effect on cats?"
Layer 5 is deep thoughts. It can get deeper. But i suppose i would quantify it as being deeply connected, by branches, to other thoughts. Deeply rooted perhaps.
When you think deeply about things, you get better at analysing problems.
That feel of talking deep with someone, but when I actually think of talking about it, it sounds like I was high. Like what kinda deep talk can a average guy like me can even have?
Something i love talking about in depth is movies, but if I'm completely candid with you I think I had to engage with YouTube essays to learn to do so effectively. You learn fast when the topic is something you enjoy. I study engineering but I recently did an English course externally just for fun, and I was so much more engaged with that then my main course. Human passion is a curse, but without it we stop being human or even animal. With no impetus to do anything, perhaps.
Your own fear is the dam wall holding back a reservoir of curiosity. Let it flow forth. Everything else will come.
The most important thing is just look for what you're into, and latch onto it, and engage with it in as many ways as possible - not just reading and study but doing activities adjacent to it.
