You don't need to watch anything about success or failure from other people, if you struggle but believe in yourself. Because that will never help you or can never give you a prediction where you will end. Their story is based on their qualifications, personality, other time period with opportunities, etc... which are different from yours. You need to critically and objectively analyze what you are doing. Because that's the only way to see where YOU are now and if it is hopeless or not to continue. Other people's stories will never have any impact on your performance. Only your own evolution, with strong and weak points, matters.
