The first one is _refuse_. Meaning don't buy / accept things you don't need. Things people don't have don't need to be manufactured, maintained, disposed of. This is the most important part.

For "reuse", vote with your wallet: get reusable/repairable things. More of these will be made and less of the throwaway kind. Usually there are options.

Always remember that you are doing this together with millions of others. Together we can change what gets made and how.
