The way to being successful gets easier when you know yourself and purpose of existence. You may be a member of this community and if you fail to understand the mission of this community or you don't post a valuable content and do anything expected of you.
You may know how to operate computers. You may know a lot about aliens or robots. You may be a doctor, lawyer, teacher or engineer. But if you fail to understands the reason your life is the way it is, and how to increase fulfilment, love and peace in your life, then all the knowledge and degrees aren't much worth having. Access yourself to know your capabilities.
