as iindra jee have said, that is true , one has to stay away from fasccist group who will uses any means to destroy , and should be close with positive guys,
but i also wants to add that one also needs to have healthy work envirn, a person usually spends 1/3 of life working , so success is guided by that too, u have to maintain healthy relationship with coworker and stay awy from senior coworker even though fren who has mentality of torturing as if u r in SS camp to junior with less exp in THAT field.
so positive ppl with positive work envirn also means success.
