You'll never know when the words you say could hinder everything you've worked so hard for only beacuse you feel that expressing yourself truthfully would be best;
You never know consequeunces from others as you cannot imagine what they are thinking;
You can never know what the future holds but can imagine what it could be;
Besides the never knowing, the thought of knowing your fate could be a scary one sometimes, but then again knowing could have you make the better choices. If you had to choose, would you rather "never know" or "know" whats ahead and coming?
