Say 3 times in the morning:

اَللَّهُمَّ إِنِّي أَسْأَلُكَ عِلْمًا نَافِعًا، وَرِزْقًا طَيِّبًا، وَعَمَلًا مُتَقَبَّلًا

Allaahumma 'innee 'as'aluka 'ilman naafi'an, wa rizqan tayyiban, wa 'amalan mutaqabbalan.

O Allah, I ask You for knowledge which is beneficial and sustenance which is good, and deeds which are acceptable.
