To move forward we have to want to more than we want to stay still and sit comfortably. To progress we constantly have to try our best. Which is not the same everyday. There are always good days and bad days. And in no way should we try to eliminate mistakes but instead encourage them. For they are truly the only way we grow. Our successes keep us driven and provide markers along the way. Our failures keep us humble and challenged because progress needs failures. And failures need progress.
We need to feel temporary glory/satisfaction after hard work but that feeling is not meant to stay. Only to motivate us further. Just as we need to feel sadness and let down, because there is no such thing perfection. Change and struggles are constant. The power truly lies in how fast you come back after you fall.
