Noisy Bus Stop; the enemy of flow

Today was my second day of implementing my happiness activity! I attempted to do my 40 minutes of colouring-in whilst waiting at a bus stop. Although I still did enjoy the activity a lot, getting into flow proved to be more difficult. I think this is due to the amount of noise and distractions that were at the bus stop, specifically having to keep an eye out for my bus to arrive. Despite this, I did eventually get into flow when I continued to colour-in on the bus. I experienced flow so much so that I nearly missed my stop to get off! Usually on my way home I feel like it takes forever, but this time I really felt that time went super quickly as I was so absorbed in the colouring-in. This relates to the dimension of flow called Transformation of Time (Jackson & Marsh, 1996, p. 19-20). Even though I really enjoyed the activity and experienced some flow, my positive and negative affect scores did not seem to change much after colouring-in. I am unsure why colouring-in today did not improve my mood, perhaps it was because I got interrupted quite a bit? My PANAS scores are below.

Before:
Positive Affect: 20
Negative Affect: 22

After:
Positive Affect: 20
Negative Affect: 21
