"Life is the sum of all your choices."
Our time is our own, though we may not think so. We are reckless with it and give it away with abandon. Perhaps we believe that if people demand things of us, that we owe them somehow. But we don't.
Saying yes is a choice, and saying no is also a choice. These are boundary setting words, and we use them for self-protection and to define the tenor of our lives.
So let's be sure to use them honestly, and straight-up, and not say yes when we mean no and no when we mean yes and leave it to others to dictate what's best for us and what is not. That's our job.
I say yes and no to things as it suits me, without apology, and without guilt or shame.
