well thts human nature duh, the more you do something the better u get at it, u ever heard of practice makes perfect, even i know riri has come a loong way vocally since her first album, she wouldve never been able to do songs like stay (especially live), whyb, only girl, mother mary, etc its natural progression of her craft and that only happens when you take what u do seriously, say what you want but she works her ass off as does beyonce
