IWTL the nature of everything. or most things.

I want to study the interconnectedness of phenomenas around us. Like how one situation is caused by a multitude of factors that may all relate to each other and each possess their own cause as well.

For example, I want to learn how the human body works and the reasons behind why it works the way it does (through evolution, biology, chemistry). Then how to apply those knowledge practically (in business, politics, healthcare) and philosophically (from what we then know, how do we approach abstract concepts like love, morality and spirituality).

You can replace the term "human body" with any other idea I may find myself curious about.

The sequence/order in which I connect and relate various fields can also be interchanged.

I'm not great at articulating what it really is that I want so I tend to beat around the bush.

I guess one way to put it is I want to see things as close to their essence/root level as possible. And to understand them enough to efficiently base my daily life and decisions upon what I know.

Among the few things that sparked this desire is my personal experience. I have struggled with my mental health and in my attempt to alleviate the difficulties by researching & reflecting, I've concluded how truly complex things can be, and how relevant that can be in terms of affecting someone/something.

I overthink a lot, so I figured that maybe by putting structure in my thoughts with proper logical reasoning (Philosophy) and a better grasp of how things around me really work (Science), I can avoid entertaining negative thoughts that originate from biased thinking and a false perspective of the world's real nature.

Also, it's just purely elating seeing beyond the surface of how things seem to be. And even better if such inquiring eyes end up finding probable solutions to dilemmas we tend to undersee.

My head is a mess and English isn't my first language. Sorry if I spouted nonsense.

Soooo, any helpful advice/insight?
