I think I've kept two.
The first one was I gave up buying light beer. It was giving me heart burn. No regrets on that one and it's been easy to keep.
My other one was to not make any more New Years Resolutions. It's been working.
My goals for my machines are the same as last year. Clear some space so I can organize my machines and display them properly. I've slowed way down on purchases. No room and the finances are tight and likely to remain that way. The good thing is it forces me to be more selective. The machine has to have a purpose like to give to a 4 H kid or fill some sort of serious want in my collection. I no longer try to get every cheap machine I see just because it's cheap.
