I am currently preparing my applications for various theoretical physics/physics master's programs in Canada and Europe. Canadian institutes typically require you to write a 1000+ words SoP. Now I am mostly certain about what to include in my SoP and how to do so. However, I am in a dilemma regarding my introduction. In particular, is beginning with a childhood story of how I was inspired to pursue the subject is a good way to start or not?
Some sources like this call it "cheap talk" whereas some sources like the one here stress having a narrative and gripping the reader from the first line on. The two suggestions might have an intersection but the latter source particularly encourages beginning with an impactful childhood experience.
In my case, the story goes as follows:
I happened to tag along with my father to an ophthalmology conference in the US. While my father was busy, I was left with this engineer colleague who was relatively free. He spent the next three days talking to me about some interesting areas of research in modern physics. We spoke about topics like QM, dark matter, LHC, and gravity. Of course, it was more of a first popular science introduction to things but it sparked my interests and genuinely led me to pursue physics. This was 7 years ago.
Now, I wish to mention this in the introduction and spend about 60 words doing so. I am unsure as to whether the above comes off as something unprofessional or unnecessary. Any help would be appreciated.
