Persistence in research is key; nature reveals its secrets only to those who are patient.
Curiosity and persistence are the driving forces behind scientific breakthroughs.

The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
The secret to outstanding achievement is not talent but a special blend of passion and persistence called grit.
