do not not do

when you're feeling down
and
it's taking you so long to get up and move,

just think about (among others)
the tasks left undone,
the praises for teammates left unsaid,
the people still unhelped,
the items in your bucket list
that needs to be accomplished.

Donald Shimoda: 
Here's a test to find out
if your mission on Earth is finished: 
If you're still alive, it isn't.
