Write it down
Write your inventory down, starting from this template, or whichever tool suits you best. Be exhaustive and follow these simple rules. Only keep items that you really need, or really love.
Use a buffer bin
Put all unwanted items in a bin. Leave them there for a few weeks. During that time, feel free to take anything back from the bin. After a while, whatever is left in the bin can be sold, donated, or recycled.
Focus on what you keep
When going through your inventory, focus on what you keep, not what you leave. Use the burning house question, or whichever trick of the mind that might work for you.
Cut deeper now
Once you have removed everything you could from your inventory, sleep over it, then try cutting deeper. Before long, it will feel like a game, and there will never be a better time to score more points.
Set a realistic goal
The journey matters more than the destination. Not everyone needs to be like Diogenes of Sinope. Set a goal that you can reach within a reasonable timeframe. When you do, enjoy your new peace of mind.
Once you reach your goal, reward yourself by refining an item from your inventory. Find the best object that your money can buy, then enjoy this little piece of luxury. Make it matter, and make it last.
Add some slack
Once you reach a lower level on the scale, keep removing a few more items from your inventory. This little bit of slack will reduce the anxiety of falling back up a level.
Include your wishlist
One way to get more slack and some extra motivation is to include your wishlist within your inventory. And if you tag your desired items accordingly, friends will know what to gift you.
