I started using YNAB—You Need A Budget—for a couple of years now. It's software that implements for basic rules about how to handle budgeting. It's much simpler than Quicken and it provides some functions that Quicken never will. Quicken is good at showing you where your money went, while YNAB will show you where your money will go.
One of the biggest helps with YNAB is the shift in thinking about where the money comes from for spending. The first rule of YNAB is to build a buffer of one month's worth of expenses, then only spend money that you earned the previous month. While you spend last months income you accumulate the buffer for next month. You always know how much money you have to spend because you already made it last month.
YNAB 3 is going to be amazing!
