You become immersed in the emotions, the fears, the joys, and the hopes of your characters. You cry for them. You laugh with them. You feel their pain.
You nudge your imagination to give them what they desire. Sometimes, allowing them to suffer the consequences of their actions is the hardest thing to do as a scribbler.
A blessing of being a scribbler is that the adventures of your characters force you to face your own fears, recognize the walls you may have constructed, and open yourself up to living an authentic life.
