My most memorable ops to leave were:
Just prior to getting baptized at 17. My dad asked had I dedicated my life to Jehovah in prayer. I didn't know I had to. So I said a quick prayer "Oh Jehovah I dedicate my life to you now." It didn't feel right, brushed the feeling aside.
While attempting to pioneer and attend college part time I was stressed out. Something had to go. I talked to my dad about it. He said that pioneering was the most noble thing I could be doing. That didn't feel right either, brushed the feeling aside.
Shortly after getting married and joining hubby at Bethel the WT article on the generation change was delivered to our rooms.
After leaving Bethel we had a 2 week window to think about our next move. Instead of leaving the borg we brushed aside any doubt and continued on for several stressful years.
