The reason why musical instruments should be taught in primary school is that they are young and quick to accept. Moreover, when they were young, they had few ideas and could concentrate on contact.

After going to college, although your acceptance has not decreased much, many things will distract you. So learning a musical instrument, especially a classical instrument, may take some effort at this time. If you just want to satisfy your own wishes, of course, you can, but you may not achieve anything.
