Areas of My Finances I Need To Review

I was hit with two, yes two costly bank charges because of insufficient fund. I felt bad, really bad, because it's really a simple matter but I missed it. The charges cost me a lot. The money could have been used to put petrol on my car for 2 weeks. Whoaaaa!

How did I addressed of this problem? First, I immediately went to my bank and enrolled my checking account to their "back up plan" where they will take money on my savings account to fund my checking account if their is insufficiency. I should have done this a long time ago!
