A smile has such a profound positive impact on those around you that it is the one thing that is used more often than sex in advertising.
So, if you want your life to change dramatically for the better, try this: Tomorrow morning, before you get out of bed, make the decision that you are going to smile at everyone you come into contact with including your spouse, partner, children, colleagues at work, the checkout person at the grocery store, and even the person who cuts you off in traffic.
Do this for just one week and you’ll be shocked at how positively those around start relating to you and how eager they are to lend a hand. – Ross Reck, author of Instant Turnaround!
