Hi, I ran into this problem when I was writing my ps too. I found that the less vague you are, the less cliche or cringe it comes off, it’ll feel more authentic - Just be technical, straight to the point.
Focus on specific issues you're interested in and discuss how the law could be used as a tool. For example, I’m interested in climate change, so I wrote about it and linked it to law by discussing an online course I took about climate litigation (practical skills I learned) and an essay advocating for environmental courts in Scotland.
Avoid just saying “I want to inspire change in the legal system” or something like that, because what does that really mean? Show, don’t tell. Elaborate, discuss court cases, your own experiences, etc. “I took part in x and noticed y which changed my view/made me feel z"
Try not to overly use the word passionate too lol.
I think though, that writing a personal statement can just feel a little cringe, I haven’t reread mines since I sent it in. I think that’s just part of the whole thing lol.
