If you run away from pain, fear, and fatigue, or ignore them, they will grow and grow stronger, but if you hear them and accept them, they will retreat.
To fill up, you need to empty yourself. When I don't give my best, I resort to the goal tired. When I give my best and reach my goal, I am filled with energy and inspiration.
The resurrection of Jesus after his crucifixion is the metaphor of love that will eternally remind us that Love is not afraid of death and always resurrects.
