The most successful, the happiest people I know of, are very comfortable (and welcoming) of change.
And when they don’t see change happening around themselves, they actively go out looking for it.

Changing the way you look at things.
Changing the way you do things.
Changing your own decision that you took so proudly, a few weeks back.
Changing your decision that you publicly announced to the world.
Changing your own self. Because you’ve found someone better: The Future You.

The ones who stay married to who they are, can never divorce who they were.
The only way to grow, is to let go. Mostly, of yourself.
