To change your destiny, the most important thing is to change yourself. One's fate is not determined by heaven or others, but by oneself. By changing your mindset and environment, your destiny will also change. There are always two selves within me: one is active, eager to try and experience everything; the other is quiet, preferring to examine and digest everything. Speculation may bring temporary success, but integrity ensures lasting prosperity. Most of the time, we live in the external world, busy with the trivialities of daily life, rarely finding time to reflect on ourselves or the meaning of life. When sudden disasters strike, they offer an opportunity that forces us back to ourselves. If we make good use of this opportunity, we will gain a new perspective on life.
