For me, I will choose "The person I admire ". I think it is easier to write. You can choose different people to write. I would choose people close to me, like my mum, dad, or grandpa, Grandma. I wouldn't choose famous people, like Obama, Donald Trump or something like that because they are not close to you. You know people who are close to you more than other famous people or celebrities ( I guess ).
Here are some points for you if you are writing the person you admire :
1. Their name ( most important! )
2. Your relationship
3. Why you choose to write them ( just a teeny bit to write)
4. Why are they important to you / Why do you admire them ( longest )
5. Have they ever done anything that had inspired you?
6. Conclusion
If you need some more advice or want help on writing another topic, feel free to ask!
Hope this helps!
