We have taken better control of our budget. I think I got the idea of "sinking funds" from a Penny Hoarder post. We figured out all our bills that are not monthly (car insurance, garbage bill, etc) and figured out a monthly payment for them. We have a separate account for that money. It broke us of the habit of raiding the savings account when we had a bill like that. So now savings grows without interference and we have money set aside when these bills come up!
