Progress is about movement, not destinations. Some days you move the ball forward. Some days you stop it from moving backwards. On really shitty days, you just try to slow it down moving in the wrong direction. It takes effort, and dilligence, and I agree it’s exhausting. We may not live to see the mountaintop, but we stand on the shoulders of giants and we try to make the world better for the next group. If we live our lives that way, we can die knowing it was worth being alive. Anything else is just killing time.
