my mom always keeps me busy,she always want me to work,study and be the best!!ok,well i am trying hard,i think i am the best already!!,but she won't stop telling those stuff and i am truely annoyed!! WHAT SHOULD I DOO?

You think you're the best.

Having such a thought would lead to narcissism in some cases, and if taken to an extreme, it can lead to an individual stopping completely on their skills, thinking that they're "good enough" when in actuality they need 더 많이 practice.

Keep a level head bro, she's doing these things because she wants 당신 to succeed. Be fortunate she's pestering 당신 at all to do these things, some people don't have anyone in their life like your mom.

Well aren't 당신 a little narcissistic?
Big deal, she makes 당신 study.
I had three exams this week. I spent all weekend studying my 나귀, 엉덩이 off, I didn't once think to myself, "I'm already the best at this, I don't need to study." And 당신 know what, I was right. My marks were in the 80's but still, that isn't "the best"
She's telling 당신 to study, work hard and try your best cause she wants 당신 to succeed. 당신 could either choose to listen to her and get decent marks on whatever you're studying for... 또는 당신 could ignore her and think you're so smart and have a chance of possibly failing/doing worse then 당신 hope.
Choose whichever 당신 want.
