Hey tericalvery64,
I've been in the same boat for nearly two years now, and am now trying to get off of it.
The conclusion I've reached is that it will be easier to live on an average of $600/month without restrictions than $733/month without the ability to save.
When you see people posting about how they can get by with so little, they're referring to having savings on hand for when things come up that small budget cannot afford. When you and I talk about getting by on $733/month, we're saying that's it. If you save, your income stops. $733/month without savings, and without the ability to save......is extremely difficult. Not impossible, but not terribly fun. At least, that has been my experience.
Something I've found essential is to have a good credit score with a lot of available credit. This acts in lieu of savings for me, only instead of being disciplined to create the savings in the first place, I simply need to be disciplined to pay off the debt afterwards. I never pay interest. My first year I had only one very low card and that didn't work so well, but since then I've had a very high amount of available credit and that allows me to, for example, buy an entire year of auto insurance at once, which gave me a discount, and earned me a $100 credit back bonus for spending so much on the new card.
Most folks 'round here frown on credit in general, moreso by using it when you can't immediately pay it off, but that's because they can save without their income stopping and saving is a far better safety net.
What I'm saying is you need a safety net of some kind--be it savings, credit, friend or family member who will bail you out of a jam....something. If you have something available as an effective safety net then yes, $733/month is doable for a wide variety of situations.
