Today I have:
Realised dd2 has left her homework planner at home so rushed it to school thuse pre-empting her getting in a row
Submitted an abstract to a conference
Done some other clever work stuff which has pre-empted problems
Given blood and not passed out
Cleared snow BEFORE it became ice
Found something left over in the frezer I can have for my tea rather than weakly buying a ready meal on the way home
Helped dd2 with her maths homework
AIBU to feel pretty blood smug about my achievements today 
Feel free to offer your -puny-- achievements if you wish to out-smug me
