Be master of your petty annoyances and conserve your energies for the big, worthwhile things. It isn't the mountain ahead that wears you out - it's the grain of sand in your shoe. - Robert Service
I have learnt through bitter experience the one supreme lesson to conserve my anger, and as heat conserved is transmuted into energy, even so our anger controlled can be transmuted into a power which can move the world. - Mahatma Gandhi
Sorrow and self-pity consume enormous quantities of energy. If you only can desist from feeling victimized by fate and look for a new solution instead, not only would you conserve old energies but at the same time also feel the surge of the new. New hope is kindled in the process. - G.R. Gopinath
