The Berkeley Ward has its own legend: J. Ed Johnson, who stood on his head.
He stood on his head at funerals, in testimony meetings and, most famously, at a Berkeley City Council meeting where his antics won the ward the permission to build a modest parking lot next to the building.
He did a lot more than just stand on his head of course, but just being a stellar Saint might not be enough to ensure legendary status. You might also need to stand on your head.
This is our stake's 75th anniversary and we've had a variety of theses and thatses to celebrate, Today, at our our Priesthood/ReliefSociety/YoungMen/YoungWomen meeting following a Stake Sacrament Meeting one of J. Ed's granddaughters showed slides of him standing on his head in cemeteries and national parks and spoke of his diligence.
So when we speak of creating a spiritual legacy for your dependents, yes provide for the widows (another Johnson trademark) but also come up with some grand, photographable quirk. Because that's the stuff of legends people. Then people will remember you.
(And if your example was in the right things, then they will also remember He whom you served.)
