Well, my ELA teacher always told me to try to avoid saying me or I... anything in first person when writing an essay. So, I would start like this.
Nuclear Bombs (sad facts about bombs, or just opinions). So why have them at all. And that would go into the paragraphs of what you might have.
but If I were to start with I believe or I think, That's something you'll have to do yourself, because "I" It'self tells me that only that person can do it. But I will give you tips! Think about what you've wanted really bad, but your parents won't let you have it. You would most definitely give them reasons to why you should have it or what benefits it would do. Apply that to your writing, and I'm almost positive, It could help anyone.
I hope this helps :3
