Could you please check my paragraph?

Setting a good example. We're looking for articles about people who are great examples to young people. It could be someone famous, or someone you know personally. Write us an article telling us who the person is, the kind of things they have done, and why you think this person is a good example to young people. We'll publish the best article next month.

Answer:

I really think my grandmother is a great example for me and in a more general way I can say that grandparents could be great examples for teenagers and younger people. They have more experience than us and they can easily help us to find a better solutions to our problems because they can maybe may have lived that these same situations before us already.

I can definitely say that my grandmother is one of the best person people I’ve ever met known. She taught me a lot of things that have helping helped me to see the different situations from more points of view. I think that, like her, in general, grandparents are great for their grandchildren and they can actually teach us a lot of things that we didn’t know before.

To conclude, I can definitely say that older people are the people from whom we have to should take our examples from. and Even if they, in some cases, seem to be against us, they are doing those things only to help us in our future lifes lives.

Very good, I just made a few corrections that in my opinion make it a little more natural. Hope this helps!

I consider my grandmother a great example to me. I think grandparents, in general, could be great examples for teenagers and younger people. They have more experience than us, indeed they can easily help us finding a better solution to our problems because maybe they have already experienced it before us. 

I can definitely say that my grandmother is one of the best person I’ve ever met, she taught me a lot of things. She helping me analysing things from several points of view. For this grandparents are great for their grandchildren as they can actually teach us a lot of things that we didn’t know before.

To conclude, I can definitely say that we should take example from older people though sometimes they might be against us, but I am sure they do it for our own good.
