Yes, don't worry. As for where it can come in handy, it depends on where you want to develop. Taking a professional route means being a teacher, playing in a band or even solo. Another way is to hold a wedding (such as blowing a loud opening ceremony to enhance the atmosphere), or to entertain yourself, or to celebrate the company's school, get-together and so on. If the eyes are not very powerful, you can learn the trumpet if you do well.
