Do you actually know yourself? Can you ever really know yourself? And if you do how did you get there? And if not how can you get there?

Or is it that we can never know ourselves ?
When I say know yourself i mean know yourself completely.

Knowing yourself means understanding your strengths and weaknesses, your passions and fears, your desires and dreams. It means being aware of your eccentricities and idiosyncrasies, your likes and dislikes, and your tolerances and limitations. Knowing yourself means knowing your purpose in life.
