Not that I sympathise much with the OP's father, but like most fathers he has the best intentions. In some cultures you can't waste your youth on frivolities, it's for building wealth to enjoy later. It works for some people and there is some merit in learning to defer happiness for periods of hard work, but you can't defer it forever. There is nothing wrong with relatively intense hobbies (the guitar can be very involving) but there is a good argument that an hour a day of practise is probably enough and securing a future needs to be done too.
