The mentality of making 10 million in ten years and making 10 million in one day is different.
If you get rich in a short period of time, the wealth comes quickly and goes very quickly. You go from a poor loser to making 10 million in one day. The demon in your heart will be released instantly. Things that you once only dared to think about but not do will immediately entangle you like a demon. You will fall into it and cannot extricate yourself until your wealth is exhausted and you lose all opportunities in life.
If you get rich slowly and make 10 million in ten years, your ability is enough to match the wealth of 10 million. You know how to make it snowball, and you will not lose your mentality because of this wealth.
