It is very common to grow up with a belief that it takes hard work to make money. This belief comes from a cultural and religious environment in many parts around the world.
And this is the exact belief that forces many traders to give back their profits to the market, simply because they don't feel they deserve that money. In trading, those cultural and religious beliefs are completely self-sabotaging because trading profits have no direct correlation with effort, yet we subconsciously fight this fact.
It's wise to remember that there's no universal definition of what money is. Money doesn't think, it doesn't know what it is, and it has no opinion about its owner. All that money is is what YOU think money is. In other words, money is whatever you think it is.
The most common definition about money is that it is a means of exchange. But this definition doesn't serve traders well. In today's world, money has many more functions than simply a means of exchange. So look around, expand your thinking and redefine what money is to YOU. That will help transcend the cultural/religious beliefs you grew up with.
