“I’m 77. More creative, healthier, busier, more curious — and more alive than I was at 40,” he continued, crediting his partner, “good lovin’,” kindness, adventure and “a little discipline” for his outlook.
He added that there are “mountains still worth climbing,” and lastly gave “the absolute refusal to let anyone else decide my worth” as a reason for why he’s thriving.
Williams also encouraged his followers to continue pursuing their goals.
“We didn’t come this far to become invisible,” he wrote. “We came this far to become unstoppable. We’re not winding down. We’re still winning — and we haven’t even played our best hand yet.”
Williams’ message of vitality comes decades after he experienced the overwhelming side of fame while “Happy Days” was at the height of its popularity.
In a previous interview with Fox News Digital, Williams recalled being mobbed by thousands of fans during a concert at the Del Mar Racetrack in California.

“I ended up face-down. On the field. Literally, I couldn’t breathe,” he said. Williams added that his shirt was torn, and he was bleeding before his manager pulled him into a nearby trailer.
“I’m thinking, ‘I don’t know about this fame stuff,’” Williams recalled.

Williams appeared on all 11 seasons of “Happy Days,” which ran from 1974 to 1984. The series also starred Ron Howard, Henry Winkler and Don Most.
The longtime friends reunited publicly in 2025 for the first time in five decades during a panel at Steel City Con in Pittsburgh.
“It feels like 50 minutes,” Howard said during the reunion. “We’re having so much fun hanging, and this is sort of our great excuse to come together.”
