If you want to be happier, less stressed, you have to work because life is always moving, throwing us punches, unexpected twists and turns. It's up to you if you are going to sit down and give up or put up a real fight and workout.
Most often you begin to see that each situation you face has many possible outcomes and some of them might be better than you imagined. Maybe you will feel less stressed and worried about the SMALL stuff and the BIG stuff and more hopeful about what life has to offer!
We don't just become who we are. The outcome is very much influenced by decisions we have made along the way, people we've observed and seeds that have been planted personally or by others about our abilities, limitations, preferences, values and principles.
The fact is that not all lies are bad, and there really is a time to lie. I'd even go so far as to say that a little lying can be healthy. As Lord Byron once said, "What is a lie? 'Tis but the truth in masquerade."
