Have Fun - I don't think there is any question that that should be the primary goal for everyone.
Enjoy Life - that's different than having fun, that's more about Gratitude - be grateful and appreciative for all the blessings and gifts and talents and inspirations that life offers you.
Help Others - well, that's why we are here isn't it? We can't do anything without others. It's the interaction with others that defines who we are. We are all in this together and helping others is how we can best help ourselves move forward through increasing the flow of positive energy all around us.
Making TONS of Cash is really a result of the other three keys to successful living. That doesn't have to be the result - maybe you want world travel or to write a great book - stick with the three key life guidelines and you will be able to follow your passion to your life purpose. Regardless of what it is though, making tons of cash should be useful in making sure you have fun, enjoy life and help others.
