I strongly recommend reading Peter Singer.

His Practical Ethics [0] and other books are excellent.

Primarily, I think it's important to very seriously think about our moral obligations to others, especially in today's interconnected world (where we not only can, but inevitably do affect others whether we like it or not).

Whenever it comes to philosophy, I always recommend Peter Singer -- just about anything by him is great. Consider Practical Ethics [1], or the recently-released-free The Life You Can Save 10th anniversary edition [2]

I find it so disappointing that people are reading Nietzsche ... why not read practical philosophy like Practical Ethics by Peter Singer? I strongly recommend any of Peter Singer's writings.
