Should I include a small thank at the beginning of my personal statement? The thank can long for one line to three lines depends on the specifics it included. In the short version, it can be like this:
I want to thank my mom, my friend XYZ and the SE community for supporting me all the time.
In the long version, it can be:
I want to thank my mom for understanding my passion, my friend XYZ for his alacrity to make my works flows better in English, and the SE community as well as other person who I have never met has spent time advising and criticizing every time I come up a new idea.
I should make clear that the school I intend to apply requires me to write a personal statement, separate to the SOP.
The personal statement should give concrete evidence of your promise as a member of the academic community, giving the committee an image of you as a person.
As a person, not a researcher.
