Being energetic is never achieved by forcing oneself, but by living with "less reliance on willpower." Truly efficient people are not more disciplined, but turn important tasks into habits—waking up early, working, exercising—once in automatic mode, they no longer consume energy. People with resources use money to handle trivial matters, leaving time and energy for more important things; those without resources must learn to control desires and reduce expenditure. Your life, essentially, is a matter of energy management: either develop habits or minimize consumption.
