Want Vs. Need

So lately we have been feeling the economy crunch more then ever.  And I have been looking into a lot of ways to save money.  I have been couponing, counting my pennies.  We have even been exploring other housing options.  Like the tiny house movement.  There are people out there that live in 300 square feet or less and seem quite content.  I am not saying I would be totally ok with that.  But the thought is there that we have waaaay more things then we actually need.  We spend more money then we actually need to.  I am starting this new year off not with a resolution, but with a promise to myself to be thriftier, more aware of my money and my needs and wants!
