That's the way most of our resolutions often go. And they leave us feeling unnecessarily guilty.
I came across a Tim Ferriss article last month that suggested instead of New Year's resolutions this year, conduct a past year in review. Basically he suggested going through your calendar from last year and asking yourself what events you attended, activities you did, habits you pursued, decisions you made etc, made you feel good. Conversely, make a list of the ones that made you feel not so good.
From there, commit to that event you loved so much. Make a plan like RIGHT NOW with that friend you went for dinner with and had such a good time with. On the other hand, come up with a plan to reduce the situations that led to negative emotions.
I went through it a couple weeks ago and it was surprisingly beneficial. Read his post here if you're curious to dig a little deeper.
