Also been a salary earner won't make you get richer if you are not investing on it, it is always about what you do with the income you have, there is this saying that says no risk no reward people that gets rich in life are also risk takers.
The rich also invest on a long time asset that will be profitable to them in time coming while other people save their money stuck in the bank without any profit the are busy making their money grow for them on what they have invest into, it can be real estate and other profitable businesses.
In my point of view, the single most important aspect for someone looking into becoming wealthy is a mix of mentality and a diligent work effort. The appropriate mindset is necessary you must be focused, dedicated, and willing to devote the period and work required to attain the goals you have set. However, it is not enough to simply work constantly; you must also work effectively. Long-lasting achievement requires thoughtful planning and sound ability to make choices. Sometimes taking sensible risks is required to attain financial independence. It is also required to assess the expected risks and benefits of any investment or company effort. Having a growth mentality, which is constantly wanting to learn and better, can also help to lay a sound basis for wealth creation.
