How do you define depth? Is being knowledgeable means having depth? or being aware of what is going on around you means having depth?
I think everyone has a certain deepness of depth. Spiritual depth, intellectual depth, knowledge on various skills. Guess the question is how deep?
Another thought is, being secure with yourself. What if you tell yourself to be secure in who you are within, but it is just self-deception? What if the problem pointed out by people around you really reflect on what you need to improve on? If you keep telling yourself that you are intellectual, you are likable, but the fact is people around you dislike you. People around you think that you are dumb? But you ignore what they say, and continue to be your old self? Wouldn't that be self-deceiving?
Then who's comment should you listen??? Maybe open to comments by who you look up to?? But what if the one that you look up to misunderstood you?? How??
