I think comfort zones are given a bad reputation in the spiritual world, though. Everyone seems to love the line, "Nothing ever grows there." I don't agree with that at all. I've done all of my best work (inner and creative) when I felt safe enough to explore my own heart and mind. Not all growth is made in the outer world through outer experiences. That's a very extroverted way of thinking. Introverted growth is important, too. I could argue it's even more important. But sometimes you grow from experience and sometimes you grow from introspection.
However, there does come a time when you have to take the things you discovered and created in your safe space out into the world. Where it is definitely not safe. I'm heading towards one of those times now. In the next few months, I'll be releasing two books. I'm re-releasing Book One, hopefully to a larger audience. And I'm finally releasing Book Two, my soul-baring book forged in the flames of my own self-hatred. It is a very scary time for me. I don't know that all the work I've put into these books for nine years combined will even matter. I don't know if readers will pick through my shiny, broken bits of soul like magpies only taking what they want - good or bad - from it.
I have no grand stories of how "worth it" putting yourself out there is. I have only hopes and fears... and the inner knowing that this is what I was meant to do. And the time is nearly right.
