Nerves of steel: requirement for being a sysadmin?



Is it just me?

Whenever I have to restart something or do some actual maintenance on a server - that my heart starts pumping and I get really really nervous.

I've heard many times people say things like:

"pain is temporary, glory is forever" (quote from a movie) when it comes to dealing with servers. Or "no pain, no gain".

Guess these are the kind of things that do improve with some experience.
