When we rush, what are we rushing for? What are we going to do with the few extra seconds the speed of our actions will acquire? I walk fast to my destination, and end up waiting longer because I was early. I rush through writing a post, and just waste the time watching TV.
When I am rushing, my mind blocks all thoughts that are coming through my head. I just mindlessly complete the task set before me, be it walking faster, or thinking more. This is where it gets sad. The mind virtually turns off to any outside source of information. So when we rush, we won't notice any hidden beauty while we walk, or miss an idea that is trying to get through to our brain.
Is the extra seconds or minutes, really worth turning yourself off from the world? Rushing may get you from A to B faster, but just remember what you're missing out on. God created the world so we could enjoy it. Why would we want to miss out on that?
