Going on the idea that thoughts create reality, or ‘whatsoever a man soweth, that shall he reap’, we can assume that the way our external reality is right now is, to some degree, a reflection of our minds. If you have a passion for reading, your living space will be full of books; if you love animals, you might have pets or work as a veterinary surgeon.
Based on this idea, we can look at everything around us in order to understand our own tendencies or thought patterns. Look at the fruits around you and you will see what kinds of seeds you planted (this may not have been the case 100% of the time, as other forces do influence our lives too, but I think we can say that, once we become adults, we are the main creators in our lives to a large extent).
So, what kinds of seeds did you plant? Was it education, love, family? Or was it work, money, competition? Whatever it was, are you happy with that? If you are, then you don’t need to make any drastic changes within. But if you don’t like what is around you, then you can do something about it: change the way you think. Believe in yourself to create a different kind of life, believe that you are on the way and that you love your life. It will come.
