The road to success is like climbing a long escalator. In NYC subway station, if you want to go up faster, you stay on the left side because the line moves along quickly. If you’re sleepy in the morning and don’t feel like moving your leg muscles at all, stay on the right. I always go up on the left, because I can’t stay still without holding onto the handrail, which is disgustingly dirty (same goes to the handrail in the train!). Anyway, have you ever felt like you were going to fall down if you just stay still on a really long escalator? I don't know about you, but I do. I feel like it’s just like our life. If you don’t climb up and keep moving, you’ll be shaken and might eventually fall down.
