Start with the water already boiling, heat on high.
Drop the pasta in the water, make sure it's fully covered in water. Unless your pot is very big you may have to wait ten seconds for spaghetti to soften and bend it.
Set a timer for 8 minutes (for spaghetti, thicker pasta may take longer)
If the pasta is bad quality, stir after 2 minutes to prevent it from sticking to itself.
When the water boils again you can lower the heat.
