In 2015 I upgraded my shades to have my prescription for less than a hundred bucks - my life was transformed. Suddenly the outside didn't cause a conundrum of sun glasses vs prescription glasses. Watching baseball, playing outside - all different thanks to that purchase.
Others on Facebook commented on this question:
Dolmar 6800i Chainsaw.. regular $750...Kijiji brand new for $275 - Philip
UE BOOM portable speaker - Kyle
New Macbook - Meghan
Board games (especially Pandemic Legacy) - Luke
Kitchenaid mixer, laptop, and condo - Danee
3 weeks in Newfoundland (and a lifetime of memories) - Don
A trip to Europe - Ryan
Upgraded seats to Ontario for son's first flight - Mark
New home - Anna
Car - Sarah
What a great list. It's not so important that we choose a particular favourite purchase and that some are good and bad, but that we remember them. Hedonic adaption occurs when we stop being grateful for things we have and start living as if we've always had them.
Don't do that! Remember your spending wins from 2015 and build on it in the new year.
