No good thing last forever, so you might as well make the most of your good times. Sit back and enjoy those smiles, take in those laughs, and appreciate the sun when it is out. Take a moment to walk or sit down and take in your environment. For we never know the day or hour when something so bad will shake up our world to the point that many will suffer and die.
Your heavenly Creator put you on this planet for good reason. You may not know the plan for your life, but I assure you that there is one. Experience a life beyond this one, go get the Holy Word of your Maker and start reading it the moment you have some free time. The more you read, the more you will begin to feel and look different.
