I prefer the term Confident.
But confidence can only come about if you are confident in yourself FIRST.
It is an inner thing that comes from a place of self acceptance.
If you are confident in/with your relationships, then you do have a voice.
Insecurity can be sensed a mile away by someone else. So you can assert yourself all you want but if you still aren't secure in what you are doing/who you are then all the books or techniques in a book won't matter IMHO.
It isn't about 'them' and how they are doing things, it is about 'you' understanding why you react to those things.
