Life
Life can be hard but never unnecessary, it'll through you down but that effort you put in to get back up will make you stronger.
You can take that one step forward sure but it's about the next step you take that really counts, because if you give up after one harsh step you'll get nowhere it's the perseverance that will carry you even further.
Life will always shift and change back and forth kinda like a wave at first rough but then slows down to show a calm front mabye if your lucky something cool could wash a shore, it's those little things that wash up that really shine through in life.
