Thanks! I think this advice - Demonstrate everything by example; don’t say directly that you’re a persistent person, show it. - is really great one!
I find this tip also very useful - In your statement of purpose, you should not only limit your paper with your goals and objectives but also provide your reader of what your potential contributions will be; this will enable the reader to know that you will be a great addition to the graduate program. It is from this article: How to Write a Statement of Purpose for Graduate School?
Hope it will help someone as well! :watermelon:
