An object, quality, or event whose presence or occurrence indicates the probable presence or occurrence of something else.
Why do people look for them?
In my experience, we tend to look for signs at times when we don't completely trust ourselves in a scary or ambiguous situation. In those moments, we want to stumble upon a supernatural clue that we're on the right track. Today, if you're among those who've left a cherished dream unclaimed, a quest half-done, a path untaken, all because you're waiting for a sign that hasn't come—I invite you to ask yourself why. Isn't the instinct in you all the sign you need? When did your inner compass stop being enough?
Sometimes, though, we look for signs in the same way we look for hope. We want a reason to stay in a relationship, to believe in a mission, to persevere through an illness, even to live to fight another day. If the voice inside your head has been uncooperative, absolutely, let this be a sign to you. There's more to you and your life than even you can fathom. Stick with it long enough to find out. In time, I hope you'll see that you were always 'sign' enough. 37.2 trillion cells. Each one endued with purpose. Each one pointing to a loving creator.
