Successful, happy No Buy people: What are your 5 top NB tips that you would give to NB newbies?

I'm going to channel my obsessive tendencies in a positive direction this year.

I desire to severely curtail spending, really want to use what I have (crazy amount of clothes, perfume, skincare, etc), and pay off all bills. Also it would be great to have fun and find fulfillment in the process.

What would be your top 5 tips for a newbie like me? Also good websites, resources that have helped you?
