I think you're growing up very well Lunar. Im barely older than you, but I have seen a lot in my short enough life (financials, love, loss, even saw some of the hardest weeks of my life last year xD). One of the things I've learned most though is that the reason why a good boss seems so wise is because of the fact they allowed themselves to accept the fact they may not know everything. A true leader is not a person who is a jack of all trades, but rather an individual who can string together people of any talent and gain the insight needed to work towards a common goal. Furthermore, they have the inner strength to admit when they are wrong and that they still have much more learning to go before their time is up. I think it is best explained by this quotes:
"When you are finished learning, you're simply finished."
Meaning that there qill always be more to learn in life. Always
