When we start living, we each want to be different from other people. We are all strong and we continue to do our job ~ more than that, we try to motivate ourselves from external sources .... yep, and we continue, until a negative moment comes quite awful and we fall in a psychic way quite weird.
Often the motivation disappears but you must be disciplined and continue to do what is right for your dream. It is important that you do whatever it takes to make your dream come true. Your attitude matters a lot, but especially your discipline - a continuous form of intense self-education for the rest of your life. This is the key to success, the way to devote yourself to constant learning for the rest of your life. This is just because self-education is a skill you form from your mindset, not something you are simply born with - an inner desire for a beneficial, super positive mindset change.
