Admit it or not , the biggest enemy to any CCIE candidate is life distractions and things that take place in our life while we should be focused only on studying. Distractions are your worst enemy , things that just pop out of no where to kill your focus zone and studying mode. My number 1 life problem is that i can never focus on 2 things at the same time , so i divide my life into periods ... This period of my life is called CCIE and any other thing that takes place can be neglected but sometimes we have to stop and focus on those important distractions because at the end of the day we're humans ... Aren't we ?
