I think it's necessary to stick with your intuitive thought to a degree... at least until rationality takes over. Keep in mind that anything, taken to the extreme, can become unhealthy. I think you've hit the nail on the head in saying that "decisions and actions based on intuition usually end up having a rational explanation" and while I've found this to be true more often than not I feel the need sometimes to act purely in rational thought. It's something that, for me, needs to be decided on the fly. I can't plan when I'll act rationally, nor when I go with my gut. It just happens.

I don't think it's in our nature as human beings to act purely in a rational realm, but some degree of it has to exist or we'd never get anywhere. When I focus on matters of personal finance and productivity I need to think and act rationally or I lose objectivity (and ultimately much more). However in my work and much of the rest of my life, intuition goes hand in hand with experience and I find myself relying on what I "feel" to be the best course of action given whatever situation.

Again, this intuitive process that makes use of my experience (and that of those I've entrusted my thoughts to) is something I've given myself over to on a rational basis. If my experience-based intuition has served me well in the past, isn't using that to my advantage the rational thing to do?
