Imagine you are stranded on an island in the middle of the ocean, you have one can of pop that is still cold for now but is getting warm increasingly fast. Do you drink the pop in one sitting while it's cold and enjoyable, or pro long it and take a little sip whenever you need it savouring the drink but making it far less enjoyable. You can compare this to life. Some people make choices to live in the now and enjoy life in this exact moment and let hope and god take over from there. Others think about their future and try to simply survive. If you decided to drink the pop in one sitting you think in the now and are living life. If you chose the sips every once in a while you are merely surviving.
