I find you need *just the right* amount of stress in life -- without some stress, some tension, there's no gravity, no accountability.
I've consistently found the most miserable people to be not just those who load up their lives with huge burdens they can't shoulder -- but on the other end of the spectrum, the people who genuinely try to live life with no cares and responsibilities.
Somehow, living the perpetual "hakuna matata" lifestyle winds just winds up leading to perpetual crisis.
