I found this amazing site on Tumblr, which is great because now I'm apart of the Social Soldiers team, using Tumblr to spread the word of this site!

I was searching for different internships online in the creative, spiritual and/or psychological realm. What a beautiful opportunity this has been and I wish the same for all of you.

So I looked at the recommendet websites and was a fan of this from the start! :)
