When you get unexpected obstacles, instead of complaining about them, turn them into opportunities. If you complain, your obstacles will seem much bigger than they are and you will attract more obstacles. 

Instead, if you turn your obstacles into opportunities you will be thankful for the obstacle. If your flight is delayed instead of getting frustrated use the waiting time to make an important call that you have been hesitating to make or write that important proposal that has been pending for so long. 

When you get unexpected obstacles, find a way to turn them into unexpected opportunities. Unexpected obstacles can be a blessing in disguise if you choose to make them so!!
