I 17 years old male, have been studying car repair for more than two and a half months. I am timid and introverted, and I have no self-esteem. I have no confidence in doing things and my voice is low.

I 17 years old male, have been studying car repair for more than two and a half months. I am timid and introverted, and I have no self-esteem. I have no confidence in doing things and my voice is low. I am not good at words and like to study with a smile. It is common for apprentices to be excluded. Never mind what they did to you. You should live up to your expectations and try to learn your skills well. Usually those useless people will laugh at those who are weaker than them. Only by arming ourselves can people look up to it. Remember: if you have words of suffering, you can achieve great things.
