Highly sensitive people can easily change their lives, start a new profession or evolve fast using every given opportunity. Of course this happens when they are healthy and didn't develop neuroses from the constant abuse they had as sensitive children.
Of course, they can always get rid of them, but this is another story.
But the paradox is that they often complain when things are changing too fast around them, so they cannot concentrate.
Of course, this does not mean that they cannot function in instability, no matter how much HSP complain, can always function, can be very efficient, they won't feel good inside them though.
There are several reasons for this need for stability, the obvious one is that they need a stable ground for stepping if they want to perform major changes. And you don't have to be HSP to need this.
But there is another one, deeper and more spiritual reason.
The Sensitive people have a close connection with the spirit, either if they are aware of it or not. And the spirit, our real nature is stable. Doesn't evolve, doesn't change, is eternal, has no beginning or end, haven't been born and will never die and has nothing to do with everything that is unstable, anything from this world.
So this memory of our real nature makes the HSP more efficient and feeling more secure. When the conditions are close to the spirit's conditions they really feel at home and can perform miracles.
And don't hurry to comment that we are too sensitive, as you always do, just think that the need for these conditions is the need for being connected with the one, and the one is all of us, you included (either you want it or not). So it is our future, or to be precise, in a timeless world, like the real one, our eternity.
