Life is a war situation. Like in war, we should always be prepared for some surprises and unknown challenges every second. In our lives, we face various challenges where, be it in careers, relationships, goals, or any other sort. These situations will really shake our true strengths and put us in self-doubt about whether we can really set ourselves back on track and fight back. These challenges are no different than facing an enemy in war, if you loose your focus a nano sec you are no more. The same is true in life, too.
