Your biggest enemy is not your competitor. Or a newbie changing the world. Or a viral trend you missed.
These are parts of life.
Your biggest enemy is someone who tells you that it is impossible for you to think beyond what lies in front of you. They make you think small because they want you to be one, even if unintentionally. It could even be your closest friends or family.
You cannot move further. Anyone who tells this to you, is the one who is your responsibility to move further away from your life.
