Yup, and to change only one thing at a time; for loads of people it's January 1st and they're like "Today is day one of my new life!". I avoid the gym in january, it's usually busy and it eases off until a month before the summer vacation.

But the trick is to start small. One day I started to reduce the sugar (and milk) in my coffee, then I had none, started going to the gym, started losing weight, went to see a personal trainer, etc. But also the other way around, one day I bought myself some craft beer (La Chouffe, my beloved) and a while later I was over a hundred kilos, lol.
