Why do you take a pic

Many a times I ask myself who do I want to learn photography. It is not a career option for me. It is not something I had always wanted to do. It’s just something I picked up last year.
Not long ago, I was writing an article. In that article, to emphasise my point, I wanted to add a pic of an umbrella that has come from the rain. A few droplets of the rain was supposed to be on the umbrella.
I wanted that picture to be clicked by myself. Obviously I could download one from google or unsplash but that does not produce the same emotion as the one that I had clicked with my own hands. The one I had edited according to my own preferences.
I could not find any.
This is when I thought why people take picture. Not because they also write something and need to hammer their point but the picture represents something to them. A lady wearing a red in autumn can mean nothing to me but it can very well remind someone of their home. Or the time when they were very emoted.
