A welcoming smile makes a world of difference.
Truth is, people like to be around those who are both happy and happy to see them. They tend to avoid those who are perpetually unhappy and consistently complain.
Be an energy giver, not an energy drainer.
It is easy to get caught up in the day to day tasks and let our guard down so be conscious of your effect upon others and greet everyone with a smile.
Added benefit? The difference you make in other people’s days will give you reasons to continue smiling.
