I probably have a long list too, but the first one that pops to my mind is
- remembering to breath
As living in dysfunction for many years I forgot how to breath properly, so now even though my life is better than in long time, I still have that tendency not to breath properly, and I get really tense, even though there is nothing that is bugging me. So, I have to keep reminding myself to: BREATH, BREATH, BREATH
and than everything looks simple and easy again.
