In the book Parallel Worlds (2005), which is really a compendium about what research has divulged to date on the topic of physics, Kaku waxes philosophical at the end of the book. He tries to place all that learning in the context of So What? What does it matter? What gives life meaning? His conclusions are fourfold:
> Work helps to give us a sense of responsibility and purpose, a concrete focus to our labors and dreams. Work not only gives discipline and structure to our lives, it also provides us with a sense of pride, accomplishment, and a framework for fulfillment.
> Love is an essential ingredient that puts us within the fabric of society. Without love, we are lost, empty, without roots. We become drifters in our own land, unattached to the concerns of others.
> Fulfill whatever talents we are born with. However blessed we are by fate with different abilities and strengths, we should try to develop them to the fullest, rather than allow them to atrophy and decay.
> Leave the world a better place than when we entered it. As individuals, we can make a difference, whether it is to probe the secrets of Nature, to clean up the environment and work for peace and social justice, or to nurture the inquisitive, vibrant spirit of the young by being a mentor and a guide.
My invitation to you: Examine your work and life against those assertions and decide if you're happy with the choices you've made so far.
If not, time to change...
