<P> `` When Will My Life Begin ? '' is a song from Disney 's 2010 animated feature film , Tangled . It is sung by Rapunzel ( Mandy Moore ) , and serves as the `` I Want '' song of the film . It is reprised later on once she is allowed out of the tower for the first time . A short reprise with Rapunzel reiterating her situation , and reasoning that `` I 've got my mother 's love ... I have everything '' etc. , was cut from the final film , though was included in the soundtrack . Lyrics are by Glenn Slater , and music is by Alan Menken . </P>
