The development of science is basically a social phenomenon, dependent on hard work and mutual support of many scientists and on the societies in which they live.

I work hard and support myself.

We don't think they're geniuses, ... We think it's a question of hard work and focus.

Where is the record that would support this? Where is the hard work that would be done? It's a big increase to go up 4% in the utility. These are increases that are 10% or above. These are not inconsequential.

Hard work makes easy reading or, at least, easier reading.

No matter what came up we never did stop. It's hard work that keep us here.
