No Worries
A person who sincerely trusts in HaShem never worries, as the verse says (Yermiyahu 17): "Blessed is the person who trusts in HaShem, and HaShem is his security. He is like a tree planted by the waterside that spreads its roots into the stream." Just as a tree planted by the waterside never worries for lack of water, so too, a person who trust in HaShem never worries because he connects himself to the Source of Good.
Lesson: A person who has perfect trust in HaShem never fears any setback or downfall, as the verse says (Ishaiah 12): "I will trust and I will not be afraid."
App: Release yourself from all worry by placing your heartfelt trust in HaShem and enjoy His unbounded and ever-present blessings, protection, forgiveness, and loving kindness!
