What do in Houston for a month.

Hey I'm coming back to Houston for winter break until late January/Early Febuary. My friend who still lives there wants to hangout with me around that time. Do ya'll have any recommendations of things and events to do in that month that doen't just involve, restuarants, bars, and shopping at the galleria area? Please keep in mind, I'm in my early 20's and I get bored easily so if you can suggest some stuff that are not too touristy but fun that be great. thanks
