Lord Krishna via 'Bhagavad Gita' says 'Man is made by his
belief. As he believes, so he is' & Buddha says 'The mind is everything.
What you think you become'. Words are different but the context is same so to
realize that 'You' are responsible for your actions and thoughts in 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
