confidence

do I have the confidence to do everything…I should say yes…after being scolding and blaming from my parents, I loose my confidence slowly…they always tell me that my studies not good and shall admit that my studies and brain not good…this makes me feel frustrated and always argue with them…I try to avoid being argue back to them and just keep quiet…that’s the good thing to keep quiet after I get scolding and blaming…in Chinese idiom, there has words that say keep quiet is gold…沉默是金…
