Cambridge Dictionaries Online defines this sort of clarity as - the ability to think clearly and not be confused. While the Oxford Dictionaries defines it as - the quality of being certain or definite. There is a clear understanding of what your decision entails, and rightly or wrongly, you have come to a decision that you are sure of. A decision that you can rest with, despite what may come. Clarity of purpose means that regardless of the consequences that may come as a result of your choice, you are certain that you've made the right judgment call. The perspective that you gained during the period of decision-making is enough.
When it comes to making decisions that may impact our careers, finances, and or, personal relationships, coming to a place of clarity becomes a wrestling match of sorts. The battle is in our mind. Facing and staring down all the worst case scenarios as they come. And that battle can be a relentless one. Tossing us back and forth like waves on a stormy sea. But the good news is that place is a temporary one. Eventually, the heart and mind are in sync and we know what we need to do.
I don't believe getting to a place of clarity is difficult. It's not. It requires an unvarnished level of honesty. Something we are not always keen on embracing. What is difficult though, is the amount of bravery it will take to act on the choice we internally know to be true.
