instinct basically is just like a thought that comes to our head and suggests what to do, which is left for us to either follow it or leave it and do what we think is better off, even as it can be correct most times.
Sometimes, it's correct. But you'd also notice that many times it is not. That's why, you can follow it if you feel that it's giving you that good thought of following it. And if you feel that you shouldn't be following it, then that's so much better for you not follow and yes, just leave it.
