Why does planning for economic growth stability full employment and efficiency involve both risks and sacrifices

A static economy must make sacrifices in order to get their desired outcome for their economy because having scarce resources prohibits an economy to have more of everything. 

To achieve goals as such, an economy must make investments which involve risks and sacrifices. 

When the economy grows to be dynamic, only then can it have larger quantities of everything with minimal risks and sacrifices involved.
