Hello!!

I propose you 4 types of problematics:

Si tu veux parler de se exploits: How his determination and courage allowed him to achieve feats.

If you want to talk about his presidential election you should say: How has Obama changed the United States and its history?

Otherwise, if you want to talk about his private life: After his presidential election, how does he participate in the political life of the country.

But if you rather want to talk about his overall life: How all his exploits, his successes, allowed to change his life and make him famous?

Tell me if it helped you and if you need anything more!

It was a pleasure writing this!
