“Change will begin the moment you take ownership of your thoughts and actions and stop making excuses.” ~~Linda A.
Your life is in your hand and it perfectly moves the way you wanted. The said luck factor or the noise as we call it in management language does not play a major role in life. Things and your life are shaped in a way you want and you are the one who can work for it. Life is a blend of success and failures and there is no one who has always seen success and no failure in life. Failing is also compulsory and it only motivates to perform better learning from the mistakes that have been made. A person improves a lot by learning from his failures. Similarly loosing exam by an inch should not lead to any trauma. It’s just that you did not performed well and every exam looks for the best. There is always a next chance.
