On the positive side, I manifested a job when I was at university. I had run out of money, and I was feeling a bit frantic, so I went to sit in the university chapel for a while (a very quiet and very calming spot). The desire for a job was on my mind, but the atmosphere was so peaceful that I just sat there and enjoyed it. When I felt better, I walked out the door, bumped into a friend who told me that the law library was hiring students (they had never done this before) - I went there straight away and they hired me on the spot
On the negative side, fairly recently I was wanting to stop a certain person contacting me. One day I was feeling very negative about this, and not ten minutes later our phone broke (just made a little tweeting noise and died) - no phone = no internet either, and we struggle to get mobile phone signal where we are. It was down for two weeks... during which time I got my wish for the person not to be able to get hold of me
