We are getting there but not quite living on last month's income. I hope to get there one day. We are saving money each month and we usually aren't paycheck to paycheck. Although, in the past we have been skirting by.

I should start using YNAB (you need a budget) software/app again to get me to my goal quicker. YNAB can really help you get out of the paycheck to paycheck situation. I didn't stick with it long enough plus I had some accounting issues that didn't make the software add up.

ETA: We do have a savings and investment accounts that we could rely on if something big happens but our income each month usually goes towards that month's expenses.
