Leaving for HK is giving me headaches

I'm off to HK on Monday for a business trip (of course, with shopping trips in between) and packing is driving me crazy. First of all, the luggage I picked can't accomodate stuff I need to bring. Dozens of business attire after, I'm swearing off packing.

On to my new, black and boring luggage, I'm still lacking space for everything I need to bring! Gah!

When will this end?
