Isn't the reason why we live just steering through the unknown and finding what will happen next. Some do more and some do less to affect it, but people usually just wonder what will happen tommorow, what will be in a year, some what will be in 50 years.
We only want to do something impactful when we want to experience the consequences in the future.
I think the not-knowing is what drives us to live. The same thing why we await death so peacefully. It's really the gate we don't know anything about and we just await to sail in.
