I'm not going to try 100% in school
Why are you not going to completely try in school?
Because I'm my own boss and I can do what I want and if people don't like my failure why should I care.
It is wrong not to value your education and take it seriously. You need to fully devote yourself to your studies or you could fail.
I think you are wrong.
You really should give it your all in school, it's very important for your future!
