As always, small things make a big impact in one's life. The two words 'Thank You' makes
a lot of difference. Just do this and see the difference for yourself. Just say Thank You particularly to these following persons. Like a pav bajji fellow or taxi/auto driver,
pani puriwala on the roadside corner or watchman or security guard, person selling vegetables, etc .
They may not reply as expected, but it will make a huge difference for them. At first, you may not feel any change, but keep trying. In US, people call the taxi drivers as "Sir".
I don't think we do this in India, subject to exceptions. Just imagine how good that driver will feel and this in turn will help you to be a better "human being". Why I am saying this, is because I have tried this and felt really good. I hope that you will also try this.
