Why do we avoid taking the time to expand our thoughts?

Is it fear of our thinking? Fear of the moment? Fear of reality?
Are we afraid that if we actually try to sort through our thoughts, that we'll be dissatisfied with some of what we discover? Or, is it perhaps worse than that? Is it possible that we cannot even come to the point of being able to decipher our thoughts?
Perhaps it's even worse than that, not that we're now at the point of not being able to decipher our thoughts, but perhaps having become wise and aware to the point of suspecting that we've never made sense of our thoughts ever at all.

Whatever the reasoning, it appears from my anecdotal experience that there is value in the endeavour. That is, I've never spent time elucidating my thinking to myself, and come away feeling as though I'm less familiar with my thoughts. Given that I must rely on my thinking to navigate and negotiate each moment that I'm engaged with, it would reason should impel one to make the effort and keep on top of their thoughts, their intention, their desires, and harness the knowledge of these things into a sensible strategy or planned actions.

Even if no planning is involve, simply having sorted through one's thoughts also yields the benefit of being better able to work with and disseminate the fabrications of one's faculties. That can only be a good thing.
