rule of thirds

I am into my 2nd week of my Personal Development Plan. For this week, I have read up on what the Rule of Thirds in Photography is. It was interesting to read up on it, because all along I only knew what the Rule of Thirds was pertaining to photography, but is only now that I realised that the Rule of Thirds applies to painting, videography and even design! And as I start noticing around me, I realise that there are a lot of advertisement, television shows that apply the Rule of Thirds.
That was some food for thought.
