My other suggestion is above.
Practice getting better.
It is written in one or more of the biographies that when Frank Sinatra started out trying to be a singer that the band members all stated that he was terrible at it. Bad intonation was cited, as well as poor phrasing, bad timing, the whole nine yards. Frank's mother actually paid for an early example of a portable PA system (Bogen?) and mic so that the local bands would hire Frank so that the female singer would have a mic.
Of course, he kept at it, took vocal lessons, hired vocal coaches, did whatever it took to get there. And get there, he did.
