THEME: last words of phrases describe a kind of bucket
GOOD ONES: One-in-a-lifetime agenda {& theme} BUCKET-LIST
BTW: AVEC is not used in English
"Pick someone else, pleeease?" WHY-ME [the clue is begging but "why me" is not begging but complaining; and while the general rule is to place end punctuation within quotes, an exception is made when the quotation is not a question but the sentence in which the quotation appears is a question.]
There is a decided 21st Century cast to this puzzle: DATA-MINING and BUCKET-LIST are terms we would not have seen only a few years ago.
DATA-MINING could have been part of the theme as there is a "mining bucket."
TANDEM-BIKE seems redundant.
RATING:

Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
