It doesn't matter what other people think. It doesn't matter if you make money. It does matter that you take your own goals and dreams and find a way to make them real.
I believe we all have certain gifts that can be used to better ourselves and others. We can say to ourselves that one day we will have the time to pursue those goals and dreams and maybe that is true. Maybe we do have to wait until we don't have pressing bills to pay that depend on that steady paycheck from a job we tolerate.
But there may be some little part of that dream that we can pursue even with our obligations.
Why is it so important to pursue our passion? Because we are meant to use our abilities. If we don't we are continually frustrated and we could become depressed and cynical and our natural joy of living could evaporate.
