We can create wealth either by investment or by a 9 am to 5 pm job.
Usually it is a job that leads to the initial capital worthy enough to start an investment. It does not mean that no bootstrapped investments are not possible but they are less and usually smaller in capital. Once your daily needs are solved then you think of investments.
With proper focus and discipline, an investment mindset enables individuals to make different ways of passive income and ultimately achieve financial independence. It is our choice how we choose to live our life.
I dont think there is such a clear cut division between who is an investor and who is a trader or a day worker. People can be all three at the same time or none at all.
The only thing that matters is the end result here. If you are working and getting a good salary enough to save up and invest good for you.
