I too have done same thing. I fixed my somewhat limited brain power while changing oil.
I have a white piece of laminated paper that I hang on streering wheel. Its asks me, Drain plug tight? Oil filter tight? Oil in engine? Oil cap back on? Everything wiped off?
I use it like the check off list NASCAR teams use.
It helps me alot. Because "sometimes" I lose my brain power.
