Expecting less and being satisfied with the divine blessings bring about a great deal of bounties and blessings. There is a Hadith from Imam Reza (peace be upon him) that says: whoever is satisfied with the less Rizq (Provision) from Allah Almighty, Allah too will be satisfied with his little deeds.
Bihar Al-Anwar: Volume 75, page 356, Hadith 12.
