I used to hate fountain pens in schools. But I recently switched to a fountain pen as an adult because my hand started to hurt when writing with ball point pens over a longer period of time. I don't have that problem anymore since using a fountain pen because I don't have to apply any pressure when writing with a fountain pen.
