Why are new beginnings scary?

The artist's studio

I've changed my studio space. My work is getting bigger and the kitchen table is just not cutting it anymore. Also, my family is getting annoyed with my painting detritus mixed in with meals. :p This, in combination with an inner push to take my art practice to the next level meant that my creative space needed an upgrade.
But its so funny... Now I'm scared to go and use it. What's up with that? Has this ever happened to you?!
Is it perfectionism? Like anything I paint from here on out has to be amazing? And what if it's not? Is it because the space doesn't feel like mine yet? Is it because it will mean that I can own the title of professional artist (which I want and do but is freakishly hard, Lol). It's like all my insecurities and self-doubts around an art career are standing with their arms crossed and blocking me from coming in.
I was not at all anticipating this as a foreseeable problem with my awesome new space.
So, of course, I call my girlfriend to discuss.
The consensus is that I should perform some ritualistic blessing of the space and invite my creative spirit to join me there instead of just my force of will spirit that I use to do laundry (the washer and dryer are just around the corner).
So now that the kids are asleep, I'm going to rummage around and look for a candle, some incense and make a big pot of tea and... gasp! I'm going to make a few marks too! Those doubts are going to have to take a hike, this lady's got stuff to do!
Wishing you all love and courage on whatever new beginning you are going through. :)
