How to say "No" gracefully

Some commitments are given to us. Being adults we deal with it. Other commitments are optional. Choosing whether to accept or decline optional commitments can be tricky. Some advice I live by, more or less successfully. 

1. If I don't immediately say "hell ya", I'm out.
2. Show me how I'm going to be wealthier, happier, or healthier or I'm out.
3. Whoa there, "that's your responsibility".
4. Or simply, I'm not interested. Tricky in some situations though. 

I turned down a band this week. Nice bunch of folks, but it just didn't feel right for me at this time. Perhaps in the future, but not right now. Which is too bad, it was a fine band, just awkward musically for me.

Best,

David 

I'm looking forward to this upcoming show though. I'll be there with bells on.
