We don't get to ask what the meaning of life is. Instead, it's our job to answer that question.
Understand that the quest for meaning, for making a contribution, can be part of what makes a meaningful life.
And, for me, a meaningful life has lots of parts. Finding your place in the economy is one part. Finding the right place in your family is another, even if that place is outside of the family.
You're never finished. It changes. As you get older, your role might change. And the world, life itself, changes.
Keep looking. Keep reading. Take risks, but don't be afraid of saying, "This was a mistake." or "I was wrong."
Then, of course, there is always drinking lots of beer.
