I too am a believer.
Last June I was on a short break in Dublin with Mrs Blue. We were staggering back to our hotel from a pub and came upon a busker. Feeling merry, I gave him all the coins from my pocket (possibly 3-4 Euro in total). We staggered on and, a few hundred yards down the road, I found a 20 Euro note in the gutter. Another few hundred yards and we were approached by a woman looking for 4 Euro for the price of a hostel bed for the night, now feeling flush I gave her a 5 Euro note. So, within a few mins of one small, but kind, gesture to a busker 3 people ended up happy. Karma or what??
