There are two things in life that you should never worry about.
It’s not worth worrying about things you can change, because you can change them.
And it’s not worth worrying about things you cannot change, because you can’t change them. Worry doesn’t help.
What does that include?
But it’s not the same as saying “Never worry about anything.” It’s the depth behind living: if you can’t change something, don’t worry about it – learn to accept it.
And if you can change things? Stop worrying. Get out there and change them.
~ Rav Gav Friedman
