I have all the training, but someone bombed our temple and then murdered several of our clone troopers. They framed me for it. The Jedi Council forced me out so that the military could try me as an example. When my Master brought back the evidence to clear me, the Council simple said they would let that be my trial. I was too hurt and confused to continue, despite that I would be a full fledged Jedi.
I often wonder if that was a mistake, but I survived Order 66 to fight another day, whereas the Jedi were all wiped out.
