Has yours failed yet?
Here's a good suggestion for how to approach doing things better in a more constructive way:
My resolution hasn't actually failed (well, the standard "read more" one is looking pretty dodgy), which was to see live music. I've never been to classical concerts before (except being dragged by parents who couldn't get a baby sitter, who no doubt told themselves it was good for me when of course I was shit bored and wanted to play with some good toys not sit in silence wondering when the very long music was going to end) - but I went to my first piano recital the other day and loved it. A great performance of the Chopin's Ballade no.1 in G Minor, a big favourite of mine, among other things. And I've got tickets booked for more Chopin in London, so I'm doing well on my 'Year of Music'.
Of course, having a resolution just to do something fun isn't very challenging, but it is wholesome and worthwhile.
What is your 'tuning fork for the brain'?
