People use to say I wasted 7 years of my life addicted to playing a game called "DotA". I believe that everything happens for a reason and one particular reason was that through those 7 years, I learnt one very important lesson; Complacency. There were countless of times even during a Grand Final competition where we were winning by a huge and ridiculous margin but because of complacency, we lost the game.
Losing is no big deal. But losing because of complacency will haunt you forever. We lost so many times due to complacency till the point that we were more afraid of our own weakness, than the strengths of our opponents.
Those 7 years have gave me such an invaluable lesson that it trained me so well to instinctively never get complacent no matter how high we climb and how far we go in our business or anything in life. So embrace whatever happens to you; because it is happening for a reason
