I'd say generally speaking, yeah. People should listen to it. However..? It doesn't hurt to ALSO use one's reason and logic, and be a bit practical about things... Especially when it comes to major life decisions! You need to involve both your heart AND your brain!
Like.. if you've got a VERY strong intuitive feeling that you should move to France..? Perhaps you should! Although it wouldn't hurt traveling there first, just to see if you'll like it... And it also won't hurt planning things out! What with money, and career prospects, and your place of residence there, and all that jazz. :)
