You found a card because
Someone super special made a decision to use their time to spread a little kindness magic. They wanted to make YOU feel special when you found this card and for you to know, that they were thinking of YOU when they left this card for you to find. I believe that we are all connected, no matter where you are in the word, we are part of a universal consciousness.
If you've read about my 'gold dust' theory, you will understand that on a subconcious (and often conscious) level, I believe every single person affects another in some way. Therefore spreading the gold dust, all of the good stuff, as far and wide as we can is such a soul satisfying way to spend my time. And hopefully you agree and are interested in spreading your own gold dust.
