Something is waiting for you on the other side of this. You can feel it. That's exactly why you're scared.
The fear isn't a warning sign. It's not your body telling you to stop. It's your body telling you this matters. The fear is proportional to how much you want it.
Nobody who ever did the thing felt ready first. Not one person. They were scared, and they went anyway, and the going was what changed them, not the preparation, not the planning, not the waiting until they felt certain.
These are for the moment before you decide.
