Positive people keep score differently than folks who are negative.  Positive people look for the good, and they count their blessings.  When they add up the pluses and minuses, they hope the good outweighs the bad, but they realize the score doesn't matter.  What really matters is whether they have a positive attitude and a heart full of love.

Negative depressed people use a defective scorecard that has only one column, and it's used to keep track of everything wrong in their life.  If something good happens, they have no place for it on their scorecard, and they quickly forget about it.  This mirror has a giant blind spot, and it just so happens that everything positive falls into the blind spot.  All of the negatives are outside the blind spot, and so the negative is the only thing they see.

If  you want to escape from this mental mirror, you must take a look at your scorecard.  If it has only one column, it's defective.  Your scorecard should have two columns that record both the positives and negatives.  When you accurately record them both, you discover many areas where good things are happening.  Once you starting noticing the positives, your mental focus shifts in a positive direction.

If your scorecard has only one column, it's time to get out your WMD (weapons of mirror destruction) and demolish this mirror.  Go ahead.  Swing your positive sledgehammer and smash this mirror to smithereens.  You will feel better when you do.
