Tracy Morgan Says He's at 75 Percent

— -- One year after surviving a horrific crash, Tracy Morgan said he's working hard to recover -- but still has a ways to go to get back to where he once was.

"I'm at 75 percent," Morgan told People magazine. "I have my good days and I have my bad days."

The comedian, 46, suffered a traumatic brain injury last June on New Jersey Turnpike after a Walmart truck slammed into the limo van in which he was traveling, and now he spends a lot of his time in speech and physical therapy, learning to walk and stand again.

"Sometimes I feel a little off, I might forget things," he added. "I want to walk my wife down the aisle. I am determined to play with my little daughter and chase her around."

Morgan said that it's his fiancee Megan Wollover and their daughter Maven that "keeps me going."

"I have a lot to look forward to: I look forward to [her] first day of school, I look forward to being married. ... I am happy to be alive," he said.
