Some answers require distance before they become understandable.

Proximity distorts. Standing inside something, you can see the detail and not the shape, which is why events often make no sense until months later when the same facts suddenly arrange themselves. The understanding was not available at the time, no matter how hard you thought about it.

If something in your life refuses to resolve, consider that you may be too close rather than not trying hard enough. Set it down for a while, deliberately. Distance is not avoidance when it is chosen, and often the answer you could not reason your way to simply appears once you stop standing in front of it.
