What a great idea! And what a great year you have had! Holey moley!
I have:
worked intensively with ds to help him recover from autism
potty trained ds (a huge accomplishment, most 4 yo's with autism are far from potty trained, and plenty of 4 yo boys without it, too)
got him wearing cloth diapers and wool pants at night again
got dd mostly dry at night
started us all on a GFCF (gluten and casein free) diet (we have backed off recently, but are gearing up to going back to strict GFCF as we are seeing things like increased bedwetting, increased behavior issues, etc)
started classical homeopathy with ds
read a ton on autism, diet, food allergies, supplements, homeopathy
finished my massage therapy schooling, took the national boards, have my massage therapy license
found two part time jobs doing massage
found a wild Alaskan salmon co-op and found money in the budget to afford it for our main meat
decluttered my house massively, giving away about 1/2 of what I previously owned, I am still going and should reach 2/3 soon
sewed clothes for my kids
simplified my life by selling my diaper cover biz
applied to an MFA in writing program
stopped eating at McD's entirely
took plenty of baths in my Roman tub

made my own soap
learned how to make bendy fairies
taught my dd how to sew
The bad:
drove WAY too much (30-60 mi/day for my son's special needs preschool)
ate at Checkers (fast food) twice - no other fast food
got too much Thai food takeout lately

went into credit card debt
and probably much more
