Discipline is very essential to wealth creation, actually you cannot implement any other principles properly without discipline. Capital is very important but without discipline, capital would be squandered unnecessarily. Discipline would see you be punctual to your business site, checkmate your employees very well and go over records periodically to identify abnormalities early enough and prevent potential catastrophe. Self-discipline is very important in your pursuit of wealth creation and it communicates seriousness and professionalism to your colleagues and subordinates and everyone would adjust accordingly when dealing with you. If workers are disciplined, the organization would record a higher productivity
Disciplined people excel faster since they are not allowing distractions of overlooking necessary steps for success. Disciplined people are not lazy since they would always do the needful for progress. Discipline is the most essential quality for wealth creation.
People who think that they have studied enough and smart to know what to do and they end up with just going "yolo" on their investments will end up losing all their money. Real money makers are people who keep doing the same thing every single day without getting bored.
Like for example, I have been working nearly everyday for the past 7 or 8 years, and try to do that every single day, even on death I still worked, even on funerals I still worked, and even when I was sick, I laid down in bed and still worked. That dedication is the way someone gets richer and if they really want to be rich then this is the way to go. There is no scenario where they will be doing better without that type of dedication no matter how "smart" they think they are.
