Never use tactical diligence to cover up strategic laziness. Without the ability to think independently and deeply, there are always leeks everywhere. Effort and hard work are the cheapest resources in this world. What the world is fighting for is wisdom and the brain, not who can move bricks faster. Always do what you understand, if you don't understand, go figure it out first. Only ignorant people always think that everyone knows, and often end up paying for their own ignorance. You need to spend money first to make yourself valuable. Poor people tend to save money and not spend what they can, while rich people tend to get results and pay for what they want. Wealthy people make money in exponential form, not linear form. They deeply understand human nature, utilize it, and control it. In terms of attitude towards money, the poor tend to hold onto power and keep more money in their pockets, while the rich tend to have the right to use it and make more money for themselves.
