Never allow a person in your life who says "NO"

I'm starting to write about my personal experience. At the age of 23 I've deep thought power for my carrier and life for public what should I do or what I shouldn't. But when I discussed with any trusted person they usually say NO, later I think why they've such negative power to say in a very bad manner. Here I can't disclose their name but that is enough, I've very good relationship with them. In my social and personal life I can't survive with those people so I unlinked them. Somewhere I read that this kind of person are not able to do their own. This is an advise from me that do whatever you like in own way but never be overconfident. Be confident and just hit your target you must be on top in your society. Thanks
