Recurring items.

We shape our tools and thereafter our tools shape us...John M. Culkin, The Medium is the Message

Aquisition

Select tools few and carefully based on values and beliefs: repair, reuse, recycle - see grinder, player, workspace or handdrill.

Before you aquire any new item ask yourself the following questions:

Do I really need it?
What exact purpose will it serve?
Is there an alternative I already own?
How much better will it make whatever I intend to do with it in comparison to the alternative I already own?
Can I make it myself?
Is it reperable? Can I repair it myself when it breaks?
Can I buy it pre-owned?
What are the environmental implications (production, transport, usage, end-of-lifecycle)?
What are the social implications (working conditions, political conditions, manufacturer ethics)?

Most items have already been produced. Try to aquire pre-owned items as much as possible.
Try to avoid items that you wouldn't burn in your own stove.
Don't fill your inventory with items for ocasions that happen once per year. Plan for the other 255 days.
