There's bucket lists to complete.
and before you say something like "i've completed mine"
have you though? have you really?
have you achieved every single thing that you've
ever wanted to? did you go out of your comfort zone again and again to finish it?
have you felt that feeling of satisfaction
after achieving everything? if your answer's no, then
that means you haven't attained everything that you've wanted to
or there's just more things for you to achieve that you hadn't thought
about doing at first.
