• The real Tree of Life was covered in actual gold, marble and gemstones, built into the wall of a mansion in Brussels.
• People who spend just a few minutes a week writing down what they're grateful for report feeling more optimistic - and even visiting the doctor less often.

It's a genuine 100-year-old masterpiece, rebuilt and re-designed with your own hands - and it doubles as a keepsake for every reason you have to feel thankful.

• Keep blank paper handy and add a new gratitude card any night of the week.
• Personalise the ornaments with the names of family, friends, or a favourite pet, and swap them out as new things come to mind.

Design your own repeating pattern using only thick and thin lines, the way Klimt did. Then take the gratitude challenge - write one thing you're thankful for every day for a week and see how it feels by day seven.
