"Richard worked very hard on his posts for you," his staff said. "He had many ideas and would work ahead … going back to each one making changes until he had it just like he wanted before posting."

Just two days before his death, Simmons gave a final interview to People magazine.

"Well, when I decided to retire, it was because my body told me I needed to retire," he said in the interview. "I have spent time just reflecting on my life. All of the books I wrote, the videos. I never was like, 'Oh look what I've done.' My thing was, 'Oh, look how many people I helped.'"

In a Facebook post on July 14, Simmons' brother, Lenny, said he didn't want fans "to be sad" about his death.

"I want them to remember him for the genuine joy and love he brought to people’s lives," Lenny Simmons wrote. "He truly cared about people. He called, wrote, and emailed thousands of people throughout his career to offer help. So don't be sad. Celebrate his life!"
