Too Kind = Stupidity ?

sooo, here i am. just arrived 'bout one hour ago in my home sweety home, Kabun Pulasan, Bukittinggi.
i'm now sit on my bed feel a bit down, confuse, and so wrong.

i just got a middle long advices and protocol from my parents.
so i'm now work in a team, which directly support someone in his job. he's an important person with many opportunity, authority, popularity, and of courseee, whealth :)
i'm the first person that he asked when he intended to make a team, so i choose all the member, despite of personal matter, i choose them because i know they have ability that this man needs.

well, because i'm on the holiday time now, i admit that i rarely doing every task of this team, but doesn't that i'm not work at all.
couple days a go he ask me to do some matter and i said honestly that i couldn't make it and suggest my team mate to him. he then call my team mate, my team mate do the task, i'm absolutely doing nothing.

i tell my parents about this. they feel a bit angry and upset. they say that i'm lose my chance to be a good member for him, to show that i'm better than anyone in my team. my parents tell me that i did these kind of things too often.
i lose every chance and opportunity way too many times which is makes me look worse in other peoples sight and gets others better than me.

i'm feeling down. idk why. maybe i'm just too overthink? or what? i feel bad for my self. i'm sad now :(
but in other way, really i want to change and be better and i want my self to have the best image i could ever get to him, because i know that my parents right, he trust me, i made him upset :(
