I agree -
To add:
Much of what technicians do is invisible to actors. I recently had a fellow student ask me what an SM does, because as she said "They never look like they're working." I pointed out that it wouldn't be very exciting to sit and watch someone compile lists and breakdowns and reports and blocking notation, but it would be really obvious if all of that didn't get done. Likewise with carps, electricians,
etc.; the folks in the cast generally are not around for the work that is done. Who wants to sit and watch a hang and focus session on their day off?
By the same token, much of what an actor does is invisible to non-actors. The psychological work of "building" a character can't be quantified or observed.
If you have a chance, try to do a little bit of everything - even if you realize that you never ever want to be onstage in the light again, do it, because then you will be able to sympathize with the work the other ppl there are doing.
