Hard Boiled Eggs on Hand

When you are going to boil one egg why not boil a dozen. That way you can just grab one for a quick snack and it's a good source of protein especially when you're not feeling your best.

Put the eggs in cold water and bring to a boil.  Once it comes to a boil some people just turn off the heat and cover the pot for 10 minutes.  But I like to leave it uncovered and simmer for 10 minutes. Either way once your time is up pour out the hot water and fill with cold to stop the cooking process.
I add an onion skin to the water while boiling the eggs. The shells go brown so that way I know which eggs have been hard boiled.

Or you could just label an old egg carton and use that.
