I'm going to start over from the beginning guitar. Pick or No Pick?

I’ve hit a wall in my trying to teach myself guitar. I believe it stems from playing piano from a very young age and having no music theory training so I can’t play by ear. I intend to start all over from page one and try to forget everything and re-learn. The method I have selected is pretty wishy-washy about using a pick or just fingers. What says the great fluther wisdom bank? Should I even do a reboot? I am stuck in too deep to quit altogether.
