The Arabic:
اللَّهُم إِنِّي أَعُوذُ بِكَ مِنَ الْهَمَّ وَالْحَزْنِ، وَالْعَجْزِ وَالْكَسَلِ
The Transliteration:
Allahumma inni a'udhu bika minal-hammi wal-hazan, wal-'ajzi wal-kasal.
The Translation:
"O Allah, I seek refuge in You from anxiety and sorrow, and from inability and laziness."
Short Explanation: It targets the mental barriers to productivity-specifically anxiety (worrying about the future) and laziness (the lack of drive to start).
