Is it useful to be intuitive and instinctual?

Yes. Because the biggest advantage is you often know of what is coming (good or bad or neutral). So, if it is bad you know to get out of the way of it if it is big like an earthquake or Tsunami or Hurricane or blizzard.

So, the main advantage you have of being naturally (or trained) as an intuitive or through your instincts is that you will survive better than others who might have had their most important qualities trained out of them growing up or in the military.

So, being intuitive and instinctual is often the difference between life and death in people's lives ongoing.

So, if you want to be able to live a long life learning how to use your deeper abilities could serve both you and your families well long term.
