I pay attention to my habits, and of course they are all around me. The diet that I eat, what time I go to bed, whether I exercise or not, how often and what times I work in the studio, etc. These kind of habits are profound in the effect they have on my life over time. A good thing is that once you have a habit it is pretty easy to keep going. So I try and form beneficial ones.
I also have less obvious habits. Ones that have to do with the way I think, my perceptions, how I approach things. This might have to do with how much time I spend with people, how I approach new situations, how I judge others and myself. These also have a profound impact on my life, but are often harder to pinpoint and even harder to change.
Because that is the thing about habits, they can work really well for you once they are in place but they can be difficult to change.
