Ilchi Lee suggests in his book Brain Wave Vibration on a wide-benefit brain

The best thing you can do to bring a sense of hope to your life is to discover a sense of purpose. But how can you know your real purpose? Maybe you have searched for that for thirty or forty years and have never found the answer.

I cannot answer that question exactly for you because it is ultimately up to you. What I do know is that whatever your mission in life, you will be of great service to humanity. I believe that every person has a great internal desire to find a harmonious way of living on the planet and to contribute something of value to the world. In Korean we call this the Hong-ik ideal, which refers to the desire to be beneficial, not just to yourself but to all of humanity.

This sort of mind-set can be a great source of continual hope in your life. People who have a clear sense of purpose are never hopeless because they always know they can make a difference, even if just one step at a time.

There is a natural progression to life that unfortunately many of us have stepped away from. It is like many of us are caterpillars who have decided not to become butterflies. Or maybe we have just forgotten that we are able to become butterflies.
