For me the quote means, you yourself can make history. You can be a very popular person, you can be the one who discovered time travel or such. Everything's possible, but only a great man can write it. Which means it's also you, your the only one who can write your own history.

This is the context. So effectively, what he is trying to convey is (in my opinion) that every common thing that you or i or any other human being has ever done has contributed to the history of mankind, but we are mostly aware of only the facts/events that have been recorded (mostly written).

Hence, contrary to popular opinion, Wilde suggests, in this case it is indeed easier to create history because we can do it while doing everyday things, but it is difficult to write about it, because the writer(historian) has to think about it, select and choose the topics/events about which he should write, and then write it in a way that people reading it can understand it as it happened.

Wilde makes his point, that (sometimes) to think about doing something is rather difficult than to actually do it.
