To show gratitude can be as simple as saying thanks, giving back what others deserve, welcoming others, honoring others, and to create goodness.
Acknowledge others as appreciation for the difference their participation and contributions make in your life irrespective of who they are and what role they hold. Try to reach out to serve them back for making a difference in their life as they did for you. This can be done through practicing hospitality of openness and providing an opportunity for them to make a difference.
Honor and respect people around you with dignity and deference in gratitude for their participation and contributions they make in your life. Step ahead on the road to create goodness!
