There's no secret.
1. Have a job with good salary.
No one wants to be poor, no one wants to work for someone else, and no one wants to do a low paying job. But the problem is that many people do not have a high education or do not have too many skills, how can they get a good salary? You try to ask everyone, does anyone criticize the good salary? But it is not easy to get there.
2. Don't save, instead of invest your money.
I also advise those who want to get rich to invest, but investing is still risky and not 100% guaranteed to be profitable. So, having no savings and putting all your money into investments is bad advice.
3. Avoid spend your money for unnecessary thing e.g. expensive food, cloth, entertain etc.
Depending on the needs and circumstances of each person, excessive savings will also cause your health to go down seriously, and without health, you cannot earn money. Save wisely, don't be too stingy with yourself.
