And fear shows up.
When we take definitive action towards change, when we put ourselves on the hook, when we leap, when we decide to put our ass where our heart wants to be, fear doesn't like it, not one bit.
All sorts of rationalisations, distractions, unnecessary details will start floating in front of us, all trying to convince us either to cancel or at least to delay the action.
Fear asks, "What good will come out of jumping in it too fast, isn't it better to spend time to prepare and plan before you jump in, nothing's going to change in a week, a month, a year, maybe it's better to wait for a while."
And when we listen to this voice, it gives us the illusion of being on our side, doing it on our behalf, of taking care of us. What it really wants is to keep things the way they are, because it is more comfortable and certain that way.
The thing is, the only way change happens is by leaping first and figuring out the ground next, not the other way around. Fear showing up is a sign that this needs to be done sooner rather than later.
