This comment made me perk up.
I've eliminated all of those things you mentioned from my life and replaced them with:
1. Alcohol 2. Traveling 3. Triathletics
In the last 3 years I've been to over 20 countries, been to every continent (except antartica), boot strapped two companies in NYC and have completed a half-ironman (and on my way to do a full next year). I realize I couldn't have done any of that if I had any of those aforementioned responsibilities.
Random, but honest (meta) question: Would people be interested in reading more about this? I always feel like if I blog about these things it would just sound like bragging.
