I've just joined a one month program by Steve Pavlina about attracting abundance into our lives.
One of the first things he went into was the notion that the Universe always acts in our best interest, without exception.
I think it would be very beneficial to keep this in mind at all times, especially when seemingly unwanted and unpleasant things are happening.
I highly recommend Steve's work. Details of the one month "Deep Abundance Integration" program here:
