The first time I walked the Camino, I had never backpacked.
I wasn't so afraid of going alone as much as I was afraid of the unexpected.
I had a kazillion questions and in the end made some good and some bad decisions.
I was told not to walk the VDLP in summer - I chose to try anyway and failed.
It was dangerously hot.
Instead of tossing in the towel, I hopped up to the
Camino Frances and had a great time!
I took WAY too much stuff and left about half of it in free boxes within the first week.
(take things you aren't too attached to because you WILL dump things and postage costs more than most items will cost to replace)
It was the trip of a lifetime and I've been back almost every year since.
Do what feels right.
You will make a few mistakes - learn from them
You will make a lot of friends.
You will come home with beautiful memories.
When you discover, on the trail, you've made a mistake, like maybe taken too much... adjust... get rid of things... change things...
And if I could give advice it would be
1) Don't stress over gear or over plan this - just use what's in your closet and go
2) Wake up each morning and give thanks for being alive and for the simple ability to walk
3) Take the opportunity to immerse yourself in a different culture - when in Rome...
4) Don't have expectations - be like a leaf in the wind and the Camino will take care of you
