An article by Carmine Coyote (Slow Leadership: Time To Pack Lighter & And Not Just For Flying) reflects on the cost of living in the past and gives recommendations on how to leave all this useless baggage behind.
"Life, like certain airlines, charges heavily for all the useless baggage you choose to drag around ... It’s worth remembering that ‘excess baggage’ isn’t just a physical attribute of modern travel. We all carry heavy, unwanted baggage around with us, in the form of obsolete feelings, useless guilt, past hurts, ancient grudges and musty attitudes that have long ceased to serve any useful purpose —- if they ever did ... Life charges us for all this; not just in terms of feeling hassled, anxious, and weighed down, but via the mistakes and messes we make because our minds are clogged by all the useless ’stuff’ ... To be worth carrying along, anything from your past needs to have a significant and positive impact on what you now value most. Activities, attitudes, or beliefs with little impact should be eliminated."
Remember though that attitudes are not that easily eliminated. Many attitudes are so deeply ingrained that sometimes you can only change the behavior you have in response to an attitude.
