Knowing yourself better

Recently, i've been thinking about an issue of knowing yourself.

So firstly, i decided to ask myself this question. Do i really know myself well? And i replied a yes doubtfully. And so i decided to ponder another question which is, does anyone ever know themselves well enough to say a yes without any doubt? And I couldn't answer myself about the 2nd question. But without answering those questions, i start to ask myself a new question.
Does a person really need to know himself/herself well even if there's a slight tinge of doubt? I could answer this. It's a yes. Why? Because people have to know what they need, want and expectat so that they can go forward to reach out to those things. And what if a person does not know himself/herself well enough to even say a yes with a doubt. He/She begin to confuse himself/herself and slowly becomes a complicated person. And i can't really help this kind of people because they simply can't help themselves.

Never mind, after all, i have no rights to tell a person to live another kind of life which is not their style. Marc and Zhiyu, feel free to answer the questions and post back to me. Thanks, as you are only the two reading my blog. Bye!
