VAN ALSTYNE -- A former Sherman football player spoke to Van Alstyne students Tuesday about perseverance and overcoming obstacles.
"It's okay things happen, but you still have greatness inside of you," said former Sherman football player Trenell Walker.
Trenell Walker knows a thing or two about being strong.
In 1995, he was a 14-year-old freshman playing strong safety on Sherman high school's varsity football team, but on October 20th of that year, his life changed forever.
One big hit sent him to the hospital and left him paralyzed from the neck down.
"Why me? I really don't want to live. What did I do to deserve this," said Walker.
He's spent the past 19 years tackling obstacles.
Ultimately achieving his dream of graduating from the University of North Texas in 2005 and getting his masters in 2008.
Now, he travels around sharing his message of hope and perseverance.
Tuesday he brought that message to Van Alstyne students.
"It's really motivating to me, to letting me know that I can conquer anything I wanna do and not let this injury affect what I want to do," said Riley Sprowl.
Van Alstyne Junior Riley Sprowl seriously injured his spinal cord last December and suffered Paralysis.
He says he and Walker have become close friends.
"He visited me in the hospital during the NFL playoffs. It was pretty good,"said Sprowl.
Van Alstyne Principal David Brown helped organize Tuesday's event and says it's good for all students to hear.
"Through determination, through motivation, they can succeed and do anything that they want with their lives," said principal David Brown.
And Walker has this advice for any time life calls an audible.
"Don't ever look down, because when you look down, you fall down. Always put your head up, because when you can look up you can get up," said Walker.
