I have heard from AdCom's directly to rewrite personal statements and experiences... the Dean of Admissions at the school I did my SMP at told me that it's viewed as lazy if you reuse. If you didn't get in last cycle, that should be an indicator that you might want to change up your primary/secondaries!
While you can keep the same shell, you should revamp the personal statement to reflect how you've grown/experiences you've had since the past cycle. I pretty much had the same first paragraph for mine but I reworded it with better language. I highly advise working with people to help you change it up; other perspectives are very helpful when it comes to finding new, clearer ways to phrase things.
