Though I am by NO MEANS an expert in this area, I have done EXTENSIVE reading on the subject. First, let me recommend a book called "The Magic of Believing." It isn't so much the energy you put forth, it's what you have in your mind. Just from your post, you are making statements that send out negative energy, because they focus on things going WRONG at this TINY moment in time. (It's all relative, said Freud)
It's a way of THINKING and you MUST turn it around to be effective. Most important, you need to understand that life is a cycle. It is compared to the ebb and flow of the tides. You will have days of prosperity and good will, but you will also have days that see a decline in the positive parts of your life. The trick is to be prepared, accept them as a NATURAL part of life and instead of lingering in the discomfort of the temporary MOMENT, LOOK to the pleasure of the next phase. Of course, this could all be tripe!
