It is a very sad state of affairs that far too many women out there have children, and then allow themselves to make excuses that use the children as a major component. Think about it: are there any of your dreams that you are not following? And if there are, are you really blaming your children’s existence (or their dependence on you, or anything else that involves them) on your personal refusal to do what you really want to do in life? With only a few exceptions (such as joining the circus or becoming a full tilt drug addict), children should not cause you problems with your goals. You need to figure out why you are using them as a justification for your own refusal to do something that you have been thinking about.
It has been said that a poorer person would say that they are never going to be rich, because they have kids. For some people, the scarcity mindset is so pervasive that to them, there is just no possible way that anyone could ever become wealthy and simultaneously take care of (and provide for the needs of) their children. To a person who thinks in that way, growing wealthy is for people who have no children. And while your goals may have nothing whatsoever to do with becoming rich (or even making any money), the idea that your children will hold you back speaks only to your own limiting beliefs.
While fulfilling your goals in life is not about money in itself, a rich person was once heard to say that he had to be wealthy, specifically because he has children. This flies directly in the face of the people who let their children be an excuse to limit themselves. After all, do you not want to give your children the best, both in material things and in examples? If you stop thinking and start doing, you might give them both.
