This one can be tough sometimes. Obviously your not always going to get along with everyone. But its never good to make enemies with anyone either. So what every you do even if you dont like someone always try to stay neutral. One time I really didnt like this one kid and were partners for an activity. I just did everyting I could to be chill and get along and everyting was ok
Unless your a genius with above a 4.0 gpa then set realistic goals for yourself. Obviously your probably not going to get an A or a B on every quiz and test you take so just try your best. Sometimes school is hard but you just got to keep going. There was this one kid I knew who was really smart and he gets almost all As but got a B one time its not the end of the world.
High School is a time where a lot of people are just starting to discover who they are and what they want to do in life. For example Johnny really liked this girl and really wanted to impress her. This girl likes guys who play football. So Johnny knowing that tried out for the football team but miserably failed.
