you can write about your life or a person you admire
Maybe write about a famous person or someone who influences you (i had this writing topic before)
ex: if you write about a famous poet, give background information about them, and talk about their influence on writing poems.
Hope this helps :)
The best way to improve the conclusion is to...:
A.) revise sentence 1 to restate a specific topic.
Sentences 2, 3 and 4 are linked smoothly and make sense. However, sentence 1 sounds too vague and lacking context. Growth experiences? OK, but how exactly? How did those experiences lead to the improvement of the speaker's math skills? Something is definitely missing.
