Invulnerable to dependencies

It's good to enjoy life's pleasures, like fine wine, Michelin-starred dining or business class travel- nothing wrong with that. However, we're not truly free if we're addicted or dependent on this, because the dependency would be in control of our lives. Can you try going without your smart phone for a day? How would that make you feel- vulnerable? Wouldn't it be much better to have the strength to resist and to be in control, rather than the dependencies controlling our emotions and lives?
