“There may not be another today, so I`ll make most of now. There may not be another of me so I`ll make the most of myself. At any moment I can start being more of the person i dream to be but which moment should i choose?”Annonymous
And as cited by Robin Sharma in his book who will cry when you die,
“Respect and Politeness in fact is the rent you need to pay for the space you occupy on this planet”.
-Robin Sharma( excerpt from Who will cry when you die)
If you can give happiness to someone merely by your polite words, then why not be polite forever.
Tunefulness : analyze whether your thought is truthful .If yes the check if its Necessity and then finally check if it is kind and when your thought have passed these three gates of righteousness then only convert your thought into words.
