Way to go man..when you compare Bangalore to other cities, its far better in terms of Cleanliness and people.
People who complain about Bangalore might have forgotten the places from where they come from. I dont understand why they complain and still, prefer to settle here.
Instead of complaining, let them think in what way we could contribute to make this a better place.
Yes, there is traffic congestion and pollution. These are the consequence of the rapid development. The government is not sitting blindly. Lots of improvements have happened wrt infrastructure and many more are due to come.
But, lets not forget the opportunities provided to us by this city. Lets do something in return. For e.g. we could reduce using polluting two wheelers. Try not to encourage corruption for e.g bribing the policeman Rs.50 instead paying a fine of Rs.100. We may end up saving Rs.50, but encourage corruption that way.
There are many more actions of ours which we could make a difference in the long run.
