If you are doing fulfilling work that is in keeping with your talents, abilities, dreams, and desires, that is your truth because it is being true to who you are. If you are in a relationship that is fun and enriching, that is your truth. If you relax in ways that are joyful and creative, that is your truth. It is the truth of who you really are, because it ultimately brings happiness and joy and the nature of the Soul is joy. Those are gauges for determining is something is right for you and is your truth.
But if you are doing grunt work just for the money and you hate it, it is also your truth for the moment. If you are in complicated, uncomfortable relationships, or find recreation in harmful ways, that is also your truth for the moment. The truth is always What Is So.
The truth is always in the present moment. It cannot be in the future. Therefore, find and engage in what brings the greatest joy to your life in all areas: Work, relationships, spirituality, and relaxation. Then you will be living your own, unique truth.
