Having money is good. Yes, you can sleep better. However, I remember when I did not have money about 35 years ago. It lasted several years. Surprisingly. I did not worry back then. Perhaps, I was too innocent or ignorant to worry. I do not know. But I was provided for. I had faith somehow I would make it through. That big man up there was watching out for me. I often wonder if folks who have money worry more, as they worry how to keep their money and make more. I suppose it is fear verses faith.
I wonder if it is an age thing? When I was at university, I was working fulltime but paying off my education - yet, times were pretty good. But, the level of responsibility in the world was different for me too - so I could forego food in favor of alcohol and a night out, and no one would care. It was similar when I came here and my friends were students -even though I was earning under poverty level, I was still able to join them, because they were too :)
