I would suggest reading some philosophy. My first year (Philosophy 101) textbook was "20 Questions", and I see it is for sale on Amazon. It's a great book, in that each chapter poses a philosophical question, such as "What is Art?" ... "Is Euthanasia ethical?" ... "Abortion" ... It's a great book - each chapter has essays from Plato to French and in-between! lol, I love to read, love to learn, and this course was my favorite of all my university classes! :D
Examining core issues of human behaviour (ie, philosophy), is a good way to explore how YOU feel about life. I stopped believing in a supreme being when I was a teenager, but didn't really examine my belief system (or lack of one) until my 30s. Taking a philosophy course really gets you thinking!
