"You try to learn the most you can, like the solar system, but I don't know what it consists of, I know that there are planets out there, but I don't know how many," he said. "It's so overwhelming. If I think of the big picture, I'd go crazy."
Bolzan continues to see the doctor about insomnia, and his terrible migraine headaches. A neuropsychologist helps him cope with the anxiety that comes with being forever disoriented.
A year after the accident, at age 47, Bolzan and his family celebrated his one-year-old memory with a birthday cake.
He will never fly planes again, and he lost the business knowledge required to run his company. But he has taken up two new passions: writing and motivational speaking.
"I think this whole process is kind of like the grieving process. At first I was very sad, very shocked, then I was scared, then I was mad, then I just accepted it," Bolzan said.
Doctors say he'll never be able to recover his memory. But Bolzan continues one day at a time, to create memories that will hopefully, last a lifetime.
