How often do you let them know?
When someone thanks you, how do you feel? Good? Does it make you want to work harder, longer, smarter, and do whatever you can to contribute to them and their business?
This is the energetic vibration of thanks. It's warm, fertile and prosperous, and it can infect people and replicate.
So whatever is showing up in your life, acknowledge it by asking “How did I get so lucky?”
It's a great way to say you're thankful and to invite more great stuff to come your way.
