what do i need to make sure i get across onmy personal insights?

I'm planning on applying to some UCs and just colleges in general so I'm definitely going to need to write some piqs, but I tend to struggle with what i need to get across in my response, and like what i need to reflect about myself and what i need to tie into my response to entice colleges and increase admissions chances. Pretty much, what makes a good piq response, what d i need to make sure i include and get across about myself, as well as what i shouldn't say. (ex for the creative one like besides just saying i like to bake because that's obvious, what do i need to say to make my response relevant and actually reflect something about me, like what are they looking for in a response.)
