Here are some tested ways to go about discernment.
What does voices within come from the friend of your best self?

Our decisions are crucially important. And not just the big ones. What we choose to think, the words we choose to speak, what we eat, the smallest actions we do add up, they matter. Every choice we make has an impact on our future selves—on our happiness, our health, our relationships, our destiny. If we know who we are, and whose we are, and what we stand for we will be able to look back on our lives at their end contentment and fulfillment, knowing that our lives have counted for something good.
