Old Or New? Both OK!

An Italian proverb says, "If you leave the old road for a new one, you know what you are leaving behind but not what you will find." This seems to advise you to stay put, because the unknown could be scary or deceitful. On the other hand, Positive Thinking encourages you to abandon old stuff (ideas, habits, maybe even your environment, if you feel the need for a change). Are these two concepts in contrast? I don't believe they are. My opinion is that, at important crossroads in your life, you should follow your intuition and dare to step out of your old ways. If this possibility entered your mind, it means that there is something to it. It means that you have to take it into consideration, because it could mark a positive shift in your well-arranged existence. But, be careful. Making a choice does not mean that you are going to be chained to it forever, as many seem to think. You step onto the new path and do your best to make it work. But if, at a certain point, you realize that it was not the optimal decision, that it did not yield the result you had hoped for, you can still go back to the old road and... try to make it work better. Let's never forget that we are free to decide what we want to do with our lives. But wisdom must be our guide. We are no children who are allowed to change their minds at a whim. We are (hopefully) reasoning adults who, by now, should be able to discriminate between what is positive and what is not.
