One thing I like about Buddhism is that it dovetails well with my skeptical, nonreligious inclination. You're expected to find things out for yourself, not take your beliefs from on high. If you don't believe in reincarnation (I do, but it's not required) you can still meditate. You're still invited to participate. It doesn't matter if you believe in God or an afterlife.
One teaching of Buddhism, that I find to be very useful, is that most of what we call "me" is an illusion. It's inherently empty. To the extent that it exists, it's dependent on so many other conditions and relationships. People get into traps. "I'm just not a happy person." "I'm a neurotic mess." "I'm a programmer, so I could never be a good writer." Bullshit. People also inflict it on each other (crab mentality) by focusing on reputation and "track record"-- this illusion that observable state reflects inherent traits rather than an interaction between a person and external conditions-- rather than real capability.
People get deeply invested in, and limited by, these identities they build for themselves and each other that actually make no sense.
Ok, rant over.
