The overall concept is getting people to make a commitment..of 8 days...consecutive..a month..a year..whatever...to do something to make a positive impact...it could be anything...volunteering at a shelter (homeless..or animal) 8 days a month..or year...or 8 days over the next 6 months...YOU make your own rules...but it's a promise..so you have to stick to it!...it could be...spending time cleaning up a community...helping senior citizens.... people with disabilities... working with environmental groups..start a peace movement...eating meatless meals 8 days a month...using no hot water for 8 days...helping to clean up streams.....just...anything...I'm sure you can think of many more ways...it doesn't have to be something big...just something you can commit to..that fits your schedule and your life....THEN...when you do it..or as you are doing it...post blogs...photos...updates..to let everyone know what your "8 days in a cherry tree" is...and spread the word..get other people involved...and before you know it....."we're causing a worldwide sensation"
