C.S.
So just do the robot...kidding. The only way to overcome it and get better, is to keep doing it. I used to go out dancing all the time and had no problem going up to the higher tiers where others could see us dance, but now am just a rock n roller, no more dancing for me. So with that, I can't move anymore.
So get out on the dance floor and tune everyone else out. Once at a neighborhood summer concert, I saw a Grandma out there groovin and a young man just danced with her nearly the entire concert. We all enjoyed her energy.
@ Grandma T, I dance with the bride and groom while I photograph them. I can't imagine what it looks like from the guest view, but I have to do what it takes to get my shots!
