Tiny drops, each individual, fall from the cloud--full sky, and then come together near the Earth to form larger drops, and then steady streams of water droplets fall together in the form of ribbons of water.
The drops form steady streams of water that fall and then hit the ground to form puddles.
The puddles come together across the world to build streams, and then rivers, and then finally giant complex oceans of water.
The rain makes a drop of water and that drop of water will make a river, and the rivers merge to create oceans.
Your actions are like water drops falling from the sky.
Each action is individual and seemingly separate, but over time each action will form consistent streams of combined actions, and will continue until it forms the river that is your life.
Every drop matters, every action matters, each is needed to make the whole.
