How can I turn constant worry into calm thinking?
Worry versus contemplation
The chitta (the mind's deeper layer of thought) is always busy with something: contemplation in a spiritual person, worry in one who is less spiritual. Such a person remains cheerful of mind as losses lessen in life.
Otherwise the essence of everyone's life is one: the chitta (mind-stuff) is always contemplating if one is spiritual; otherwise the chitta is always worrying, if one is not so spiritual.
