To stay safe when driving, walking or riding a bike, we have to keep our eyes looking forward, toward where we are going. The same goes for our thoughts: if we keep our eyes fixed on our difficult past, or all of the reasons why something won't work, or on all of the negatives of a situation, it is impossible to move ahead with any kind of optimism or momentum. When we consciously focus on what brings us joy, our minds will inevitably follow, and that is a vital decision we can make to choose happiness for ourselves, both now and in the future.
