The first piece of advice comes from a volunteer fireman in a short TED Talk.
The 2nd piece of advice comes from Doc Searles (and others who expounded on his nugget of wisdom).
"Tell ya what. I’m fifty-seven years old, and I’ve been pushing large rocks for short distances up a lot of hills, for a long time. Now, with blogging, I get to roll snowballs down hills. Some don’t go very far. But some get pretty big once they start rolling. See, each snowball grows as others link to the original idea, and add their own thoughts and ideas. By the time the snowball gets big enough to have some impact, it really isn’t my idea any more. ....Anyway, at this point in my life I’d rather roll snowballs than push rocks.
The blogger then quotes what Hugh MacLeod says about it. HERE.
