Why is gratitude essential for goal setting and well being? How can we express gratitude? Life coach Mervin Straughan explores what gratitude is and why it's integral to a success mindset. He also introduces the Grati-tuna© – a tuna fishbone – from his 2020 self-help guide 'Imagine Life As Three Bus Journeys.' He devised the Grati-tuna for enabling us to capture everything for which we're thankful in life. Each time we express gratitude, it moves us to a more positive state and it helps to build resilience.
