Planning is a great way to foresight and manage the ups and downs that you may face . However cautious and thorough planning it may be, plans do fail at times.
When a plan fails, most people are unable to accept it. This is because most plans are designed to be fixed, allowing little or no room for changes or adjustment. When things take an unexpected turn, people feel they lack the capability to handle them.
Whether your plan is big or small or at the starting stage or near to completion, if ever it fails, don't lose heart. Calm your mind, reassess it and think of new ways to go about it.
