Here's what will happen as you try to finish your Christmas shopping this week

WHEN it comes to buying presents this week, just be mindful of the 80-20 rule. The 80-20 rule applies to buying done from now on, ie 80% of available thoughtfulness, energy, and time is spent buying the first present on the list. Then you realise what’s left to be done and it all starts to get compressed into shorter and shorter decision-making processes and by the end, everyone’s getting vouchers.
This is not a present-buying guide. I would never be so presumptuous as to tell you what to buy — yet, skip to the very end for that — but I will tell you what is likely to happen this week. And forewarned is forearmed, sometimes (though I am not encouraging you to employ a stiff forearm across the collarbone of a fellow shopper as you both spot A Thing That’s In). Speaking of which, these are the different types of presents you will be buying.
