alacrity/əˈlakrɪti/noun – brisk and cheerful readiness.

Attention is like energy in that without it no work can be done and in doing work it is dissipated. We create ourselves by how we invest this energy. Memories, thoughts, and feelings are all shaped by it.*
Mihaly Csikszentmihalyi

A “flamboyant” worker, exuberant and excited, is willing to risk control over his or her work: machines break down when they lose control, whereas people make discoveries, stumble on happy accidents.**
