Time doesn’t stop because we want it to. We exist because we’re here, but just because we’re here, doesn’t also mean we exist. You can go through time and change nothing, or you can go through and change everything. But change isn’t inherently a good thing, and anyone who uses the word as though ‘change’ also means ‘good’, has never seen something so quickly go backwards and wrong. We all change, and change is what we all do. The difference, is making sure those changes mean something. You can’t change the weather when it rains, but you can always use an umbrella.
