Thanks for sharing Eugene. Yeah I totally agree with this, if we get that excited feeling then it's an opportunity to go with it and see where it takes us. It can be scary because it's the unknown, but that's also what makes these moments so rich in potentials.
One thing that takes discernment and some subtlety, is telling between the 'butterflies in my stomach' excited/nervous feeling and the other feeling that means 'no'. The second one is more of an uneasiness I guess, that's what I would say if I had to describe it.
Learning to trust the bodies signals is a whole other world.
I think the ability to tell the difference between the two comes with experience, if you are ready to take risks and act, you will get hurt, but you will learn both consciously and subconsciously, with time refining the intuition.
