The original quote is this
“Be soft. Do not let the world make you hard. Do not let the pain make you hate. Do not let the bitterness steal your sweetness. Take pride that even though the rest of the world may disagree, you still believe it to be a beautiful place.”
Which quite often gets misattributed to Kurt Vonnegut. And I am quite often, unashamedly proud of that.
It comes from a project I ran from 2007 to earlier this year called I Wrote This For You and the last entry explains how it started and why it ended.
