Change is best!

You cannot always change others but you can always change yourself!

I know sometimes it's problem with them and how can we change? But we can! By changing our reaction or opinion towards them or by leaving them on their own!
Few people love to learn from their own mistakes so let them fall and then understand rather that we tell them to be cautious and ourselves loose our self-respect when they don't think that it's important for them to change.

Sometimes it's worth not doing something for those who don't need it than we show our care to them.
