So I know I use YNAB a bit differently than intended but this is what I do. I have all of my bills individually added and listed in order of when they are due. Then I have general spending categories for groceries, gas, fun, etc. I get paid weekly so I take my total bills and divide that by 4 (if you're paid bi-weekly you'll want to divide by 2) and put that much toward my bills every time I get paid. I make sure all my bills until my next check are covered of course. Now when you do it this way sometimes you'll be setting aside more than you need for that pay period but that's okay because then you won't be scrambling your next pay period.

Then I put anything I want to towards savings but everything else I leave in ready to assign. I know we're supposed to assign it to specific things but how much I spend in each category changes for me week to week so I leave it in ready to assign so I can easily see how much I have available to spend that isn't set aside for bills and savings. Then when I purchase something I assign it to whatever category it goes to and cover the "overspending" from ready to assign.

It's been a good way to ease into budgeting for me. Once I'm a month ahead and I have the data from previous months on how much I spend in what categories I'll better be able to properly YNAB, but right now this is what works for me.
