The one thing I should wish I knew more about were all the different good spirits of the Camino and all the honest walkers out there compared to the daily life and people in here in the "ordinary" life. You may wonder how to find your way, how to get this and that, but as soon as you have gotten your credential (You get it in in most churches/albergues) and then you are on your way, and everything falls into place. You will not be alone out there unless you want/need to. If you don't want to share your thoughts with anybody else, simply walk alone and look introvert...
You will meet people who become your friends, and/or you walk in your own solitude or together with other pilgrims, just as you choose/want, and you will find that the camino is perfectly doable, and if you need help, much WILL show up in front of you. Have no fears; You will get the help you need while you're on the way. You will be walking inside a friendly society. I wish you a splendid camino.
You are gong to experience some extremely good friends, and some beautiful walks, all by your own. You may even find your own mind out there. Very likely, actually.
Buen Camino to you!!!
