Different believes about spending money, how to solve?

I am an Aquarian Rooster (an Artist and Writer) drawn towards creative work. My husband is a Gemini Snake and works as a Medical Psychologist and Writer. Our only area of disagreement and difficulty is finances. I am a saver, with a strong need for feeling future security. He tends to live for today, enjoys nice things, material possessions and buying, and seems to not have concerns about future financial security. How can we come to a balance in this area?
