i had trouble writing the personal statement, and im sure many others have as well. I guess one advice is to not be creative at first. I guess because its often hard to start of with something catchy and creative that you'd like to have. So outline the major points you want to say and add the little creative aspects later. Plus you're limited to a few thousand characters so its probably best you answer all the questions fully before adding anything else (assuming you're working through PTCAS). One advice I got from my professor was to think of an event or a time where you demonstrated leadership, maturity, responsibility, and growth (common aspects wanted in a graduate program). Once you find your own personal experience, tie that in with how that will help you in the future, and why those personality traits will benefit you in the future. Good Luck and Best Wishes!
