The power of those two words is taking center stage at the virtual "Mattering Summit".
It was created by Wyndmoor's Cheryl Rice who began the "You Matter Marathon" a decade ago, by handing out cards that say the phrase.
The free summit will run from Tuesday, May 12th to Thursday, May 14th.
It will include 25 speakers in 25 minute sessions spread out across the three days.
You'll hear about how to put mattering into practice, for yourself, at home and work, and in your community.
