Happiness can be thought of as a carrot on the stick game. We are ever chasing it never really being fully satisfied. Whether it's love, fame, money, jewels, adventure, we chase and chase and chase.
But that is not a bad thing necessarily. Greatness comes from being unhappy with our current circumstances. That is quickly followed up with the need to better, to have better. Money is just one of those tools that we can use. It is a means to an end. Not the end. We all need capital for our dreams to become a reality. The problem is when money becomes the end, in which case we will never be happy.
Honestly, the best we can hope for is to be happy with every each small individual win we make in life. That also includes waking up in the morning, having health, and the people around you, who love and care for you.
