Legacy doesn't matter... but today does.
And tomorrow, and the next day. Because what we do each day does affect tomorrow's today. If that makes sense. I think we should consider what we "leave behind" in terms of how our actions are going to affect others - even if we don't know them.
I do think it's incredibly unlikely anyone will read old stuff on the internet while there is a trillion hours of new content being produced every day.
I agree. Except, my daughter might be interested. It again comes down to who actually cares. Strangers don't.
