People are motivated by the sense that they are building something. What they’re building does not seem to be particularly important. 

What does seem to matter is that people have a consistent sense that each problem they solve somehow “builds on” the set of problems they have solved in the past.  With this “sense of meaning” intact, people will happily work very hard so long as their other basic needs are taken care of.

Without the “sense of meaning,” no amount of coercion or money will get people to solve problems in a creative fashion.
