You can't change? You can!

Today I was talking with someone who said every so many minutes: "people can't change, so I can't change." It was almost like a mantra. A destructive one.

When people say I can't change they mean: I don't want to change, and my automatic response is starting to search for the reason.
Is it fear? Do they gain by not changing?

I think everyone can change.

The Dalai Lama says:

"When we really feel that there is some need to change,
then our minds can change.
Wishing and praying alone will not transform your mind,
but with conviction and reason,
reason based ultimately on your own experience,
you can transform your mind.
Time is quite an important factor here,
and with time our mental attitudes can certainly change."
