Knowledge in philosophy, particularly strict epistemology and logic (binary vs trinary), with the intent to constantly apply this knowledge through life. Enough knowledge in psychology and neuroscience such that you can have a decent understanding of how the human mind works (and ways in which it fails imperceptibly). Time spent in psychedelic and spiritual realms seem to be quite practically useful for this type of learning. Systems thinking - gain an understanding of the presence and importance of unseen systems, and the unseen complexity and causal relationships contained within. For example, we live in a system (that itself is composed of numerous subsystems), and each of us is a system (our mind, itself composed of two distinct parts, the conscious and subconscious, each consisting of numerous subsystems). Such things are very easy to forget in real time, but even if remembered, our perception of the state and behavior of these systems is extremely inconsistent (sometimes even backwards) with how they actually are. Realize that outside of the hard sciences, we are rarely dealing with facts, but rather coarse approximations, and that this is often completely not realized (to put it mildly). It seems this can be decently learned from an abstract perspective, but the degree to which this abstract knowledge can be drawn upon in real time seems extremely inconsistent. (Meta) In general, people's minds (and broad Western culture) often seem to find these sorts of ideas instinctually repulsive, so exercise disciplined skepticism with those who dissuade you from study.
