The 6 of Cups is about having confidence in something. It is the number of security and harmony. In the suit of Cups this means to be in harmony with yourself.
Learn to have enough confidence in yourself so that you will attract good events in your life. You don't always need to pull the cart yourself.
You're content with yourself, you know that after a storm the sun will probably shine, and you radiate this to others who will think better of you because of this.
Try to stay realistic, it's not wise to have blind faith in that everything will turn out fine. Sometimes you need to pull or the push the cart yourself indeed.
