Finally checking back here after holidays :-)
@Lilbert: interval training is so straining (but effective) that good for you for doing that!
I realized that trying to form any kind of new habits is doomed during the holidays. Well, for me it was. I'm sure that if I had put effort into it, I could've just continued making changes, but that didn't really happen. At least not with food! :-) Then all of a sudden yesterday I felt like I can't eat anymore and just stopped. So I had a whole day of fasting, which unfortunately also meant that it was difficult to get some sleep, but it kickstarted my diet habits again.
My new year's resolution was to try to do the harder thing at least once per day, even for just one small thing. I have such a huge tendency to procrastinate and choose instant gratification. I've managed to get rid of so many big problems that I've been letting myself relax and not get into the nitty gritty details on how I mismanage my life. But now I think I've had enough rest and it's time to become more disciplined. Out of love, not as a punishment!
So, approximately five months to go! I hope everyone has had a nice start for their year!
