I think I did well this weekend, too -- However, I only finished half of the tasks I set out to do.
Well, even if I did my best,
'The only reward for doing your best is doing your best.'
I think so.
I say this as I am on the verge of retirement, but this is a good and true statement.
More accurately, "The only reward for a job well done is that you did it" (Angie, in Hamidashikko).

Oh, there was one more thing.
You can "falsify history."
This one may be a 'tasty reward' in its own right -- even if it is an illusion.
