Holmes appeared in good spirits as he streamed himself with his mom on Facebook Live Sunday afternoon.
"You just got to stay focused and keep pushing," Holmes said in the video.
Holmes was released from the hospital back in September and was cheered at a gathering in Galveston County.
In August, Holmes began defying the odds as video showed him standing and exercising for the first time since the traumatic incident.
More recently, Holmes was able to go home for the first time since March to celebrate Christmas with his family.
The shooter, Cassandra Damper, is charged with aggravated assault causing serious bodily injury and tampering with evidence.
