Not really. I like to challenge myself with different poses no matter how tough they are. It helps me build up memory so that if I have to use the same poses again, I know what to do.
Most of the poses I had difficulty with involves hands and as much as I'd like to avoid them to draw faster, I'd always tell myself, "Ah, screw this! I'll try to get this right no matter how many trashy hands I make!" I think the most number of trashy hands I made before I got it right was around less than 30 or 40. I dunno. Too many to count. 
Nah, that's understandable, especially if you're still learning and trying to finish your drawing before deadline.
