My Dad, now and then, drops these beautiful nuggets of wisdom.

"The best impressions are when people expect them the least." - John Brady

It doesn't take much to leave a good impression.

• Care.

• Be Thoughtful.

• Serve Others.

• Be Authentic.

• Don't Show Off.

Nobody expects this treatment from anyone. But, just because nobody expects it, doesn't mean you can't show it.

Do this all the time.
Leave a great impression.
