It's such a valuable principle which is so simple and with a little conscious effort can become part of who you are.
Enthusiasm is contagious. You can encourage and uplift someone who is having a bad day just by your own excitement for the day. If you greet someone with a wide smile and a genuine excitement that they're there, its almost impossible for them not to be affected by that. Excitement and enthusiasm for life will make those around you feel it too.
Love life, and those around you will learn to love it too. They will look forward to seeing you, and start to reciprocate that excitement. If you can make someone feel valued, important and worthwhile, you have made a friend. Every personality is different and everyone shows their enthusiasm just a little bit differently, but we can all recognize when someone is genuinely happy to see us. it takes so little to communicate that, and so little to make someone’s day happier and brighter. It’s a shame we don’t take advantage of that huge opportunity more often.
It's an upward spiral because the more enthusiastic you are with people, the more they are with you, and then that makes you feel good, and you become even more enthusiastic, and you keep going up and up. There’s no way of knowing the limits of that!
