To be a warrior, means to do what is necessary and good, in your judgement, despite fear, doubt, difficulties and uncertainty.
Being a warrior does not have much to do with overcoming your external enemies. It has a lot to overcoming your own self.
It might mean following your own path, it might mean joining a group of like minded people.
It might mean that you take a huge risk and put your life and other things on the line, or it might mean taking the safer path and taking the 'cowards' way out. (Only you whether or not it was a judgement based on fear)
It also means accepting your own failures, and learning from it; not dweling in your past mistakes as if it defines you.
It might mean seeking help when needed, it might mean giving help when un-wanted.
It might mean you pass harsh judgement or be harshly judgement, or just the opposite, be praised by others. That is not the end goal.
It'll most likely require making difficult decisions and commiting; trusting your own judgement.
