'Short-term memory loss' is nice to have if that helps us to recover from those memories that act as barriers to lead a happy and peaceful life! [Author: Gopi]
Differences in my viewpoint: To-do list - you've to work on them and you'll not be efficient if you pile them up & Wish list - you can pile them and if you work for it, you'll be more effective in what you do!
"Smile" in your face might not show how Sad you are at heart but ignites a Spark in others. So, make others Happy as possible and there will be instances where they will make you feel Better. -Gopi
