Your fingertips will hurt for weeks learning guitar until calluses form. That’s your hands agreeing to stay.

Sore fingertips are not a sign of doing it wrong. Skin thickens where it is used, and the three weeks it takes are the body deciding this is going to be a regular feature of your life. The discomfort is the cost of entry and it has a known end, which makes it easier to sit through.

Count the weeks rather than the sessions, and keep them short while your hands adjust. Fifteen minutes a day will build calluses faster than two hours on Sunday. When it stops hurting you will have passed the point where most people stop.
