Aiming for perfection usually assumes comparison against some standard of judgment. You can only start with where you are and what you are right now. For some people the idea of a longer existence may be comforting. When I am gone, there may be but a trail of bubbles left in the swirling waters of aggregate acts of the mass of humanity.
I agree with the BKs (although not their reasoning) that this is a magical time, this unique moment in time, and whatever you want to do, do it now. Don't wait for the next life. Tomorrow never arrives.
