Just keep playing and you will form callouses on you fingers. It took me about 2 months. I played with heavy strings at first and then switched to lightweight 80/20 Golds.
I played pretty much all day yesterday and couldnt wait to get up today and start again... As soon as I touched the strings I nearly hit the roof my fingers hurt so much!! Is this normal? Should I rest them (I REALLY don't want to) or should I suck it up and power through until I earn my callouses?
