Everything was impossible until somebody did it.(Все было невозможно, пока это кто-то не сделал.) что по вашему значит эта фраза?​

I believe that the point is that nothing is impossible,everything takes its time and we need to understand this.We believe that someone will decide everything for themselves, because we don't believe in others,and we think that this is a waste of time and that it is impossible.But when he reaches his exceeding goals, we realize that all isn't lost, that there is still hope.Therefore, nothing is impossible.
