Know your wants and needs.
One trick to get used to connecting is to place deposits on top of everything. So, once the monthly bill arrives, do not immediately compile a list to be paid. But set aside some money for you to save first.
That way, once you have compiled the entire bill and prepared the money, you unconsciously already have money to keep, if it turns out the bill is not too much. But, if it turns out enough bills, you can take some of the money you have saved the first time.
