Took me awhile to build up callouses. When I first started playing I would practice everyday till my fingers hurt so bad I couldn't play anymore. I just couldn't help myself. Took about a month that way. Now I have skipped almost a week and them suckers aren't going anywhere. Don't forget you can incorporate reading about theory and such in your practice routine when your fingers hurt but you still want to keep learning.

I did notice though after a week or so without playing an acoustic just electric that when I did pick up the acoustic my fingertips would know it. However it was nothing and I mean nothing like in the beginning.

Long story short I wouldn't try to rush it it is just part of the learning process. Once built up you can play all day without any tender nous. Good luck,
