It’s ok to admit that you don’t know everything. It’s not your job to know everything. Your mental and emotional health is just as important as your physical wellbeing. There’s no need to apologize for everything. Sometimes stuff happens and that’s ok. You don’t have to please everyone. You will never be able to in the first place. You are young and you're learning. Bad grades happen. No one is perfect. Your IQ isn’t what defines you. Choose your friends wisely because they make up a huge part of your life. Be willing to ask questions. Learn about other people. Finally, remember God is there even when it seems like no one else is.
