Spend quality time with your love ones; treasure the moments you have with them. Make sure they are aware of their importance in your life. Laugh with them, value their time, be slow to anger but quick to love. Those with children, take time out of your busy schedule, set it aside specifically for them. Remove any and all distractions so that you can focus on them. They can tell if you're focused on them or not.
Time is precious and so are those who mean the most to us. Giving your undivided attention is priceless.
