First, indentify if you are stuck. Create metrics if needed ("if I don't advance this cuantitative variable in a week, then I'm officially stuck").
Second, when you are officially stuck, you need to make a formal and conscious decision to stop fully or keep going. Your current projects should have this 2 posible states: Stoped (with an optional of "until X happens") or Running.
PS: You also need to formally determine where the finishing line is. Otherwise, you'll never finish.
