Yours is obviously spending side driven. Spend less through “puratanic” thinking. I agree with the discipline to some extent but with all one-sided though processes - there are pitfalls to your logic.

By only buying to satisfy extreme need, one does not contribute to the wheel of life, economic improvement and development of the marketplace.

More importantly, the act of minimizing “the nut” for some people tones down their ability and drive to be be productive in day to day life. It becomes too easy to not quantify true costs of time, material, payrolls etc. when one removes all or most of the economic pressure in life.

All greatness comes from need. Often times, the greater the need, the more dire the situation, the greater the event.
