Know Thyself
Why does this need to be done? That is nothing but knowing yourself is more difficult, especially to conquer personal ego.
In many cases, finding and knowing people is far more than just diving into our hearts. Because of this, there are many people in this world who don't know themselves, especially not recognizing it.
Knowing yourself is very important, especially as a strong foundation for self-development. In other words, the more we know ourselves, the easier we develop the potential we have in achieving success.
