Many people need to focus to get things done in life and this is an honourable quality to have. Sometimes this devotion or fixation on an unit element blinds you to the surroundings. This applies as well when it comes to happiness. We tend to focus on that single fibre of joy and overlook how it was built and where it came from. When looking at the bigger picture we can understand the many elements that are intertwined that lets us enjoy our lives in a broader perspective.
Look at the tree but enjoy the forest.
