Just be yourself.
As someone one the other extreme of height, I will tell you it is probably better to be shorter than way taller, since I can't fit into anything.
Nursing a bruise on my shoulder from hitting a pipe under a rig this AM, in fact.
I also went to Six Flags in San Antonio and couldn't ride Batman because I was too tall. Pissed me off and made my nephew cry.
Also, T-Mag has articles today calling us "seven-foot tall genetic anomalies with crazy levers." Gee, thanks.
