Feeling discouraged about my age

Does anyone feel discouraged about age as an artist? I am by no means old (just turned 30 - I'm a female rock singer/songwriter and play in a band), but I feel like all these pop stars who are able to find success in music are like 20 years old. Sometimes it makes me want to stop making music all together knowing that in the industry age seems to be such a determining factor of someone's success. It makes me feel like I'm "past my prime" so why try? 😭
