Really, a question worth to ponder. Thank you for asking me this! Hmmm, a part of growing up I wish I had known before is I am not only growing up physically, but also mentally, both of which can’t be stopped, and I have to find a way to deal with its hardships, such as understanding the importance of responsibility, and somehow it is truly something crucial. I should learn to take ownership of my actions and decisions as well, recognizing that they have consequences, and having a sense of self-awareness to help me understand my own feelings is a must. The last one is, my parents are getting old too.
