Hong Kong (CNN) -- It's an essential part of any trip, an activity we all take part in.
Yet almost none of us are any good at it.
Souvenir buying -- instead of being an enjoyable part of the travel experience, it too often becomes an obligatory slog.
The global economy for ill-conceived souvenir purchases is staggering.
In 2012 alone, travelers spent a total of US$2.3 billion on souvenirs that were subsequently ignored, unused, unappreciated, unworn, discarded, disliked, ridiculed and/or stuffed in bottom drawers and backs of closets never to be seen again.
Worse, travelers wasted 427 million aggregated hours fretting over the purchases of pointless doodads, knickknacks, tchotchkes, gewgaws and dust gatherers.
OK, we made all those figures up, but given all the "Singapore is a Fine City" T-shirts, Chairman Mao cigarette lighters, plush koalas and inflatable jumbo airplanes cluttering the CNN Travel office, we're pretty sure people spend a lot of money and time on desperation purchases that unfairly burden recipients with the obligation of hanging on to these dubious prizes for years to come.
The good news is that it's easy to improve your souvenir-buying savvy.
Avoid the common shopping mistakes above and your family, friends and coworkers might actually start looking forward to your return home for a change.
