If your thinking about what it means to live simply check out this website. It might be different than you thought.
A thought I agree with from the Live Simply Website: Words of Wisdom at the beginning of Lent(25 Feb 2009) :
We know we are beginning to live sustainably when we acknowledge, mention and delight in the love of those who sustain us; when we commit ourselves long term to others or another; when we give ourselves to our fundamental purpose in life.
We live sustainably when we value what we have and need, not what others want to sell us. We recycle what is not needed, we do not recycle the relationships and commitments that underpin our very existence.
We know we live sustainably when we find ourselves increasingly sad about the destruction of the created world that has been given to us as a gift by God.
