Do you belive that good mood bring you good luck?

I think it is the image that you impress on your subconscious mind. If you are thinking good, positive thoughts, good things happen. I you are thinking that everything is terrible, nothing is going your way, everyone hates you, etc. those things are liable to occur.

I get depressed sometimes and think negative things but then everything seems to get worse. I keep a paper on the cupboard in my kitchen that says,

"Divine right action is mine. Success is mine. Wealth is mine. Happiness is mine. God's river of peace flows through my mind, body, and activities, and whatever I do will prosper. I know my thoughts are creative. As an engineer plans a bridge, so am I planning prosperity and happiness now. I believe implicitly in the law of the Bible, which promises, 'Ask, and it shall be given you, seek and ye shall find, knock and it shall be opened unto you.'(Matthew 7:7)"

It is from a book by Dr. Joseph Murphy. I try to read this everytime I am working in the kitchen, to remind myself to stay positive and things will all turn out good.

I don't know about it bringing you good luck per say but i think a good mood leaves you open to better experiences and opportunities in life because you are being positive.

Let us put it this way: If you are in a good mood you will
notice even the smallest "good" thing that is happening around
you and in your life. If you are in a bad mood, you complain
almost about everything; even the smallest thing. That's how
it works. Naturally, if you feel depressed your mind is negative
in everything about life, thus, you are starting to believe that
you are having bad luck. My friend, I was diagnosed with depression
in 2006 and was taking medication. When I decided to stop my medication
all I did was pray, relax, exercise, program my thinking into positive
things only, look at the more beautiful side of life..... Though I still
feel depressed sometimes I always manage to get out of it and be happy
again. Life is how you make it. Be happy.

Yes it does at times.If i started the day with a great smile it brightens up all my day and if you start the day with with your face frawn or something like lonely it sometimes carries the whole day.It doesn't make sense but it happens.

i really think so.
i believe it is the brain wave influence it, have you ever heard of this theory?

yes... i believe a positive projection of yourself reflects positive resposes from others as well... just like when you smile at somebody, usually, that person reciprocates the gesture...
