Want me to recite hundreds of lyrics and accompaniment? You want me to learn twenty musical instruments? How can I learn music easily? How to protect your voice?

It's completely personal. You can introduce about twelve kinds of musical instruments, but if you want to master them in a short time, don't think about it. It is not as difficult as expected to report a better vocal class at the score level. Voice, don't smoke, don't drink, eat Chili, don't often stay up late, not bad.
