However efficent you  may be, however effective your plans may be, however dedicated you may be, you may not get success for want of cooperation of many external factors(simply we name this luck).
Dedication, hard work are must for any success besides a pinch of salt called luck.In fact, there is no word like luck. The disadvantageous factors combined tohether which obstructs our success are itself called bad luck.
