The calluses come before the good songs. Sore fingers are proof you’re on schedule.

Discomfort early on is usually your body or your mind building the equipment the skill requires. Sore fingertips are not a sign you are doing it wrong, they are a receipt for the hours, and they come before anything sounds good. Nobody skips the part where the work costs something and returns nothing yet.

If what you are learning hurts a little right now, treat that as being on schedule. Keep the sessions short and regular so the soreness stays useful. In a few weeks the same amount of playing will not cost you anything.
