"Thousands of miles is the first step, and there is dust in the mountains. My road is the same, and my line is getting more and more expensive. " Bai Juyi not only emphasizes "starting from a thousand miles", but also emphasizes "getting better every day", that is to say, there will be new gains, new thinking and new progress in the accumulation of daily efforts. If you just repeat the skills you have learned day after day without thinking, it is not dedication, and the ambition you pursue cannot be successful.
