An algorithm used in my life

I make a sandwich for my breakfast in the kitchen, as follows:
1.Find several pieces of bread and lettuce in the refrigerator on the west side of the kitchen, otherwise return to step 1 tomorrow.
2.Find the egg in the cupboard on the south side of the kitchen,otherwise return to step 1 tomorrow.
3.Find the frying pan on the stove on the north side of the kitchen,otherwise return to step 1 tomorrow.
4.Find the bottle of oil in the cupboard on the east side of the kitchen,otherwise return to step 1 tomorrow.
5.Pour oil into the frying pan on the stove with the proportion of 1/3 of the pan.
6.Turn the burner knob counter-clockwise  as far as it will go. If the burner doesn't light, turn the knob clockwise as far as it will go and return to step 1 tomorrow.
7.When the oil becomes hotter, strike the egg and put it on the frying pan.
8.3 minutes later, the egg becomes over-hard, and then turn the knob clockwise as far as it will go,otherwise return to step 1 tomorrow.
9.Add lettuce and the over-head into bread and then eat it!
