It is true. You are to follow your own heart. You are your own drummer. This is not to say that you are to necessarily follow all of your immediate impulses. You may want another ice cream sundae. This does not mean you have to say Yes to another ice cream sundae.
You may want with all your heart to have a new car. This doesn’t necessarily mean you are to buy one just now. Sometimes it isn’t a choice, or a good choice for you. It is not a bad thing when you cannot afford something. Not having the money helps you to discern and make decisions.
It is good for you to follow your dreams. Of course, all dreams aren’t about spending money. In the relative world, everything depends.
Common sense also has its place. Nor can it be said that common sense is to rule. Whose common sense is it? Yours or someone else’s? Results are not always the test. What you see as good results or unfortunate results may not tell the tale. Eventually, someone would have discovered the sought-after New World. If Christopher Columbus had initially listened to the advice of the world, it wouldn’t have been Christopher Columbus who discovered America.
It is not always so easy to know where your heart is leading you or whether it is truly your heart at all. Many a man and woman have fallen in love. Their hearts were certainly happy, and yet how many of these happy hearts married great happiness?
