You are definitely not too late man.

Glen Johnson never put gloves on until he was 20 and he was the light heavyweight champion. Tarver never turned pro until he was 28 and he just beat Johnson. Guys come off of being drug addicts and prisoners.

There are a lot of stories of guys who started late and from a bad place. Boxing is one sport where it often comes down to who wants it more, who's got the heart, and who's willing to sacrafice the most.
