Water

Water.
People think water is always laid back but it struggles internally for eternity to maintain the facade of laying still. Water is furious. When an external force pushes it, it is doing all that it can to pull itself together and try to stay as calm as possible. There are times when it can't take it anymore and that's okay, every stream has a different threshold that develops over time but it makes sure that it stays until it has found an able body to project itself on to.
Be like water.
