What is the appropriate supplication for success at work and protection from envy?

The supplication that protects one from people's envy is reciting the Mu'awwidhat (Surahs Al-Ikhlas, Al-Falaq, and An-Nas) three times in the morning and in the evening. Among the supplications that help achieve success in affairs is: "O Ever-Living, O Sustainer, by Your mercy I seek assistance; rectify all my affairs for me and do not entrust me to my soul for the blink of an eye." Also, the supplication: "O Allah, guide me and conceal my faults."
